+
+## Build
+Current implementation is designed to build three differt codec (AV1, H264, HEVC) with the same code (note AV1 is stub right now).  To build each codec, we run setup with different codec name.
+
+To build the COM based H264 codec, you can use the following command to setup the build (please run the setup under the mesa folder, and by default the output will go to c:\bin)
+
+```
+meson setup build/ --pkg-config-path="C:\lib\pkgconfig" -Dgallium-d3d12-graphics=disabled -Dintel-elk=false -Dmicrosoft-clc=disabled -Dllvm=disabled -Dvalgrind=disabled -Dlmsensors=disabled -Dzlib=disabled -Dzstd=disabled -Dxmlconfig=disabled -Dgles1=disabled -Dgles2=disabled -Degl=disabled -Dgbm=disabled -Dglx-direct=false -Denable-glcpp-tests=false -Dopengl=false -Dgallium-drivers=d3d12 -Dgallium-xa=disabled -Dgallium-vdpau=disabled -Dgallium-va=disabled -Dgallium-mediafoundation=enabled -Dc_args="/guard:cf /we4146 /we4308 /we4509 /we4510 /we4532 /we4533 /we4610 /we4700 /we4789 /wd4703" -Dc_link_args="/guard:cf /profile /DYNAMICBASE" -Dcpp_args="/guard:cf /we4146 /we4308 /we4509 /we4510 /we4532 /we4533 /we4610 /we4700 /we4789 /wd4703" -Dcpp_link_args="/guard:cf /profile /DYNAMICBASE" --default-library=static -Db_vscrt=mt -Dc_std=c17 -Dcpp_std=c++17 -Dmicrosoft-clc=disabled -Ddebug=false --buildtype=release -Dwarning_level=2 -Dvideo-codecs=h264enc -Dmediafoundation-windows-dll-name="msh264enchmft" -Dmediafoundation-store-dll=false -Dgallium-mediafoundation-test=true
+```
+
+To build the COM based HEVC codec, use the above command but replace all instances of h264enc with h265enc to setup the build.  Similarly for the pending AV1 codec, replace h264enc with av1enc.
+
+For debug builds, change the debug/buildtype to true, e.g.
+
+```
+-Ddebug=true --buildtype=true
+```
+
+For building the unit test, add the following option to the meson setup.
+
+```
+-Dgallium-mediafoundation-test=true
+```
+
+To build, run the following command from the mesa folder.
+
+```
+ninja -C build/ install
+```

+//! @defgroup bitwise Bitwise Inspection and Manipulation
+//! Bitwise helpers to improve readability and reduce the error rate of bitwise operations.
+//! Several macros have been constructed to assist with bitwise inspection and manipulation.  These macros exist
+//! for two primary purposes:
+//!
+//! 1. To improve the readability of bitwise comparisons and manipulation.
+//!
+//!    The macro names are the more concise, readable form of what's being done and do not require that any flags
+//!    or variables be specified multiple times for the comparisons.
+//!
+//! 2. To reduce the error rate associated with bitwise operations.
+//!
+//!    The readability improvements naturally lend themselves to this by cutting down the number of concepts.
+//!    Using `WI_IsFlagSet(var, MyEnum::Flag)` rather than `((var & MyEnum::Flag) == MyEnum::Flag)` removes the comparison
+//!    operator and repetition in the flag value.
+//!
+//!    Additionally, these macros separate single flag operations (which tend to be the most common) from multi-flag
+//!    operations so that compile-time errors are generated for bitwise operations which are likely incorrect,
+//!    such as:  `WI_IsFlagSet(var, MyEnum::None)` or `WI_IsFlagSet(var, MyEnum::ValidMask)`.
+//!
+//! Note that the single flag helpers should be used when a compile-time constant single flag is being manipulated.  These
+//! helpers provide compile-time errors on misuse and should be preferred over the multi-flag helpers.  The multi-flag helpers
+//! should be used when multiple flags are being used simultaneously or when the flag values are not compile-time constants.
+//!
+//! Common example usage (manipulation of flag variables):
+//! ~~~~
+//! WI_SetFlag(m_flags, MyFlags::Foo);                              // Set a single flag in the given variable
+//! WI_SetAllFlags(m_flags, MyFlags::Foo | MyFlags::Bar);           // Set one or more flags
+//! WI_ClearFlagIf(m_flags, MyFlags::Bar, isBarClosed);             // Conditionally clear a single flag based upon a bool
+//! WI_ClearAllFlags(m_flags, MyFlags::Foo | MyFlags::Bar);         // Clear one or more flags from the given variable
+//! WI_ToggleFlag(m_flags, MyFlags::Foo);                           // Toggle (change to the opposite value) a single flag
+//! WI_UpdateFlag(m_flags, MyFlags::Bar, isBarClosed);              // Sets or Clears a single flag from the given variable based upon a bool value
+//! WI_UpdateFlagsInMask(m_flags, flagsMask, newFlagValues);        // Sets or Clears the flags in flagsMask to the masked values from newFlagValues
+//! ~~~~
+//! Common example usage (inspection of flag variables):
+//! ~~~~
+//! if (WI_IsFlagSet(m_flags, MyFlags::Foo))                        // Is a single flag set in the given variable?
+//! if (WI_IsAnyFlagSet(m_flags, MyFlags::Foo | MyFlags::Bar))      // Is at least one flag from the given mask set?
+//! if (WI_AreAllFlagsClear(m_flags, MyFlags::Foo | MyFlags::Bar))  // Are all flags in the given list clear?
+//! if (WI_IsSingleFlagSet(m_flags))                                // Is *exactly* one flag set in the given variable?

+    * A wil::task<T> / com_task<T> is a coroutine with the following characteristics:
+    *
+    * - T must be a copyable object, movable object, reference, or void.
+    * - The coroutine may be awaited at most once. The second await will crash.
+    * - The coroutine may be abandoned (allowed to destruct without co_await),
+    *   in which case unobserved exceptions are fatal.
+    * - By default, wil::task resumes on an arbitrary thread.
+    * - By default, wil::com_task resumes in the same COM apartment.
+    * - task.resume_any_thread() allows resumption on any thread.
+    * - task.resume_same_apartment() forces resumption in the same COM apartment.
+    *
+    * The wil::task and wil::com_task are intended to supplement PPL and C++/WinRT,
+    * not to replace them. It provides coroutine implementations for scenarios that PPL
+    * and C++/WinRT do not support, but it does not support everything that PPL and
+    * C++/WinRT do.
+    *
+    * The implementation is optimized on the assumption that the coroutine is
+    * awaited only once, and that the coroutine is discarded after completion.
+    * To ensure proper usage, the task object is move-only, and
+    * co_await takes ownership of the task. See further discussion below.
+    *
+    * Comparison with PPL and C++/WinRT:

+    * [1] Resumption in the same COM apartment requires that you include COM headers.
+    * [2] Synchronous waiting requires that you include <synchapi.h> (usually via <windows.h>).
+    *
+    * You can include the COM headers and/or synchapi.h headers, and then
+    * re-include this header file to activate the features dependent upon
+    * those headers.
+    *
+    * Examples:
+    *
+    * Implement a coroutine that returns a move-only non-WinRT type
+    * and which resumes on an arbitrary thread.
+    *
+    * wil::task<wil::unique_cotaskmem_string> GetNameAsync()
+    * {
+    *     co_await resume_background(); // do work on BG thread
+    *     wil::unique_cotaskmem_string name;
+    *     THROW_IF_FAILED(GetNameSlow(&name));
+    *     co_return name; // awaiter will resume on arbitrary thread
+    * }
+    *
+    * Consumers:
+    *
+    * winrt::IAsyncAction UpdateNameAsync()
+    * {
+    *     // wil::task resumes on an arbitrary thread.
+    *     auto name = co_await GetNameAsync();
+    *     // could be on any thread now
+    *     co_await SendNameAsync(name.get());
+    * }
+    *
+    * winrt::IAsyncAction UpdateNameAsync()
+    * {
+    *     // override default behavior of wil::task and
+    *     // force it to resume in the same COM apartment.
+    *     auto name = co_await GetNameAsync().resume_same_apartment();
+    *     // so we are still on the UI thread
+    *     NameElement().Text(winrt::hstring(name.get()));
+    * }
+    *
+    * Conversely, a coroutine that returns a
+    * wil::com_task<T> defaults to resuming in the same
+    * COM apartment, but you can allow it to resume on any thread
+    * by doing co_await GetNameAsync().resume_any_thread().
+    *
+    * There is no harm in doing resume_same_apartment() / resume_any_thread() for a
+    * task that already defaults to resuming in that manner. In fact, awaiting the
+    * task directly is just a shorthand for awaiting the corresponding
+    * resume_whatever() method.
+    *
+    * Alternatively, you can just convert between wil::task<T> and wil::com_task<T>
+    * to change the default resumption context.
+    *
+    * co_await wil::com_task(GetNameAsync()); // now defaults to resume_same_apartment();
+    *
+    * You can store the task in a variable, but since it is a move-only
+    * object, you will have to use std::move in order to transfer ownership out of
+    * an lvalue.
+    *
+    * winrt::IAsyncAction SomethingAsync()
+    * {
+    *     wil::com_task<int> task;
+    *     switch (source)
+    *     {
+    *     // Some of these might return wil::task<int>,
+    *     // but assigning to a wil::com_task<int> will make
+    *     // the task resume in the same COM apartment.
+    *     case widget: task = GetValueFromWidgetAsync(); break;
+    *     case gadget: task = GetValueFromGadgetAsync(); break;
+    *     case doodad: task = GetValueFromDoodadAsync(); break;
+    *     default:     FAIL_FAST(); // unknown source
+    *     }
+    *     auto value = co_await std::move(task); // **** need std::move
+    *     DoSomethingWith(value);
+    * }
+    *
+    * You can wait synchronously by calling get(). The usual caveats
+    * about synchronous waits on STA threads apply.
+    *
+    * auto value = GetValueFromWidgetAsync().get();
+    * 
+    * auto task = GetValueFromWidgetAsync();
+    * auto value = std::move(task).get(); // **** need std::move

+    This class provides a very similar API to `wil::unique_event` but doesn't require a kernel object.
+
+    The two variants of this class are:
+    - `wil::slim_event_auto_reset`
+    - `wil::slim_event_manual_reset`
+
+    In addition, `wil::slim_event_auto_reset` has the alias `wil::slim_event`.
+
+    Some key differences to `wil::unique_event` include:
+    - There is no 'create()' function, as initialization occurs in the constructor and can't fail.
+    - The move functions have been deleted.
+    - For auto-reset events, the `is_signaled()` function doesn't reset the event. (Use `ResetEvent()` instead.)
+    - The `ResetEvent()` function returns the previous state of the event.
+    - To create a manual reset event, use `wil::slim_event_manual_reset'.

+    Cases not handled:
+      - Functions that need the lock held, but fail to specify this fact by requiring a lock required parameter need
+        to be found via code inspection.
+      - Recursively taking a lock, when it is already held, is not avoided in this pattern
+        - Readers will learn to be suspicious of acquiring a lock in functions with lock required parameters.
+      - Designs with multiple locks, that must be careful to take them in the same order every time, are not helped
+        by this pattern.
+      - Locking the wrong object
+      - Use of a std::lock type that has not actually be secured yet (such as by std::try_to_lock or std::defer_lock)
+        - or use of a lock type that had been acquired but has since been released, reset, or otherwise unlocked
+
+    These utility types are not fool-proof against all lock misuse, anti-patterns, or other complex yet valid
+    scenarios. However on the net, their usage in typical cases can assist in creating clearer, self-documenting
+    code that catches the common issues of forgetting to hold a lock or forgetting whether a lock is required to

+
+// RESULT_DIAGNOSTICS_LEVEL
+// This define controls the level of diagnostic instrumentation that is built into the binary as a
+// byproduct of using the macros.  The amount of diagnostic instrumentation that is supplied is
+// a trade-off between diagnosibility of issues and code size and performance.  The modes are:
+//      0   - No diagnostics, smallest & fastest (subject to tail-merge)
+//      1   - No diagnostics, unique call sites for each macro (defeat's tail-merge)
+//      2   - Line number
+//      3   - Line number + source filename
+//      4   - Line number + source filename + function name
+//      5   - Line number + source filename + function name + code within the macro
+// By default, mode 3 is used in free builds and mode 5 is used in checked builds.  Note that the
+// _ReturnAddress() will always be available through all modes when possible.
+
+// RESULT_INCLUDE_CALLER_RETURNADDRESS
+// This controls whether or not the _ReturnAddress() of the function that includes the macro will
+// be reported to telemetry.  Note that this is in addition to the _ReturnAddress() of the actual
+// macro position (which is always reported).  The values are:
+//      0   - The address is not included
+//      1   - The address is included
+// The default value is '1'.
+
+// RESULT_INLINE_ERROR_TESTS
+// For conditional macros (other than RETURN_XXX), this controls whether branches will be evaluated
+// within the call containing the macro or will be forced into the function called by the macros.
+// Pushing branching into the called function reduces code size and the number of unique branches
+// evaluated, but increases the instruction count executed per macro.
+//      0   - Branching will not happen inline to the macros

+    //! would fail-fast when this is encountered, but it would do so AFTER FunctionWhichMayThrow() is already off of the

+    //! selectively to isolate issues a component may be having with unknown/unhandled exceptions.
+    //!
+    //! The ability to vary the SupportedExceptions that this routine provides adds the ability to track down unexpected
+    //! exceptions not falling into the supported category easily through fail-fast.  For example, by not supporting any
+    //! exception, you can use this function to quickly add an exception guard that will fail-fast any exception at the point
+    //! the exception occurs (the throw) in a codepath where the origination of unknown exceptions need to be tracked down.
+    //!
+    //! Also see @ref ResultFromExceptionDebugNoStdException.  It functions almost identically, but also will fail-fast and stop

+    //! const wchar_t constArray[] = L"foo";

+    //! map.find(constArray);
+    //! map.find(nonConstArray);
+    //! map.find(static_cast<const wchar_t*>(constArray));
+    //! ~~~
+    //! The first four calls in the example above use `WindowsGetStringRawBuffer` (or equivalent) to get the string
+    //! buffer and length for the comparison. The fifth example uses `std::wstring::c_str` and `std::wstring::length`
+    //! for getting these two values. The remaining three examples use only the string buffer and call `wcslen` for the
+    //! length. That is, the length is *not* deduced for either array. This is because argument types are not always
+    //! perfectly preserved by container functions and in fact are often captured as const references making it
+    //! impossible to differentiate const arrays - where we can safely deduce length - from non const arrays - where we
+    //! cannot safely deduce length since the buffer may be larger than actually needed (e.g. creating a
+    //! `char[MAX_PATH]` array, but only filling it with 10 characters). The implications of this behavior is that
+    //! string literals that contain embedded null characters will only include the part of the buffer up to the first
+    //! null character. For example, the following example will result in all calls to `find` returning an end
+    //! iterator.
+    //! ~~~
+    //! std::map<HString, int, wil::hstring_less> map;
+    //! const wchar_t constArray[] = L"foo\0bar";
+    //! wchar_t nonConstArray[MAX_PATH] = L"foo\0bar";
+    //!
+    //! // Create the key with the embedded null character
+    //! HString key;
+    //! THROW_IF_FAILED(key.Set(constArray));

+    //! map.find(constArray);
+    //! map.find(nonConstArray);
+    //! map.find(static_cast<const wchar_t*>(constArray));
+    //! ~~~
+    //! In order to search using a string literal that contains embedded null characters, a simple alternative is to

+// STL common functionality
+//
+// Some aspects of STL are core language concepts that should be used from all C++ code, regardless
+// of whether exceptions are enabled in the component.  Common library code that expects to be used
+// from exception-free components want these concepts, but including STL headers directly introduces
+// friction as it requires components not using STL to declare their STL version.  Doing so creates
+// ambiguity around whether STL use is safe in a particular component and implicitly brings in
+// a long list of headers (including <new>) which can create further ambiguity around throwing new
+// support (some routines pulled in may expect it).  Secondarily, pulling in these headers also has
+// the potential to create naming conflicts or other implied dependencies.
+//
+// To promote the use of these core language concepts outside of STL-based binaries, this file is
+// selectively pulling those concepts *directly* from corresponding STL headers.  The corresponding
+// "std::" namespace STL functions and types should be preferred over these in code that is bound to
+// STL.  The implementation and naming of all functions are taken directly from STL, instead using
+// "wistd" (Windows Implementation std) as the namespace.
+//
+// Routines in this namespace should always be considered a reflection of the *current* STL implementation
+// of those routines.  Updates from STL should be taken, but no "bugs" should be fixed here.
+//
+// New, exception-based code should not use this namespace, but instead should prefer the std:: implementation.
+// Only code that is not exception-based and libraries that expect to be utilized across both exception
+// and non-exception based code should utilize this functionality.
+
+// This header mimics libc++'s '__config' header to the extent necessary to get the wistd::* definitions compiling. Note
+// that this has a few key differences since libc++'s MSVC compatability is currently not functional and a bit behind

+// STL common functionality
+//
+// Some aspects of STL are core language concepts that should be used from all C++ code, regardless
+// of whether exceptions are enabled in the component.  Common library code that expects to be used
+// from exception-free components want these concepts, but including STL headers directly introduces
+// friction as it requires components not using STL to declare their STL version.  Doing so creates
+// ambiguity around whether STL use is safe in a particular component and implicitly brings in
+// a long list of headers (including <new>) which can create further ambiguity around throwing new
+// support (some routines pulled in may expect it).  Secondarily, pulling in these headers also has
+// the potential to create naming conflicts or other implied dependencies.
+//
+// To promote the use of these core language concepts outside of STL-based binaries, this file is
+// selectively pulling those concepts *directly* from corresponding STL headers.  The corresponding
+// "std::" namespace STL functions and types should be preferred over these in code that is bound to
+// STL.  The implementation and naming of all functions are taken directly from STL, instead using
+// "wistd" (Windows Implementation std) as the namespace.
+//
+// Routines in this namespace should always be considered a reflection of the *current* STL implementation
+// of those routines.  Updates from STL should be taken, but no "bugs" should be fixed here.
+//
+// New, exception-based code should not use this namespace, but instead should prefer the std:: implementation.
+// Only code that is not exception-based and libraries that expect to be utilized across both exception
+// and non-exception based code should utilize this functionality.

+// STL common functionality
+//
+// Some aspects of STL are core language concepts that should be used from all C++ code, regardless
+// of whether exceptions are enabled in the component.  Common library code that expects to be used
+// from exception-free components want these concepts, but including STL headers directly introduces
+// friction as it requires components not using STL to declare their STL version.  Doing so creates
+// ambiguity around whether STL use is safe in a particular component and implicitly brings in
+// a long list of headers (including <new>) which can create further ambiguity around throwing new
+// support (some routines pulled in may expect it).  Secondarily, pulling in these headers also has
+// the potential to create naming conflicts or other implied dependencies.
+//
+// To promote the use of these core language concepts outside of STL-based binaries, this file is
+// selectively pulling those concepts *directly* from corresponding STL headers.  The corresponding
+// "std::" namespace STL functions and types should be preferred over these in code that is bound to
+// STL.  The implementation and naming of all functions are taken directly from STL, instead using
+// "wistd" (Windows Implementation std) as the namespace.
+//
+// Routines in this namespace should always be considered a reflection of the *current* STL implementation
+// of those routines.  Updates from STL should be taken, but no "bugs" should be fixed here.
+//
+// New, exception-based code should not use this namespace, but instead should prefer the std:: implementation.
+// Only code that is not exception-based and libraries that expect to be utilized across both exception
+// and non-exception based code should utilize this functionality.

+// STL common functionality
+//
+// Some aspects of STL are core language concepts that should be used from all C++ code, regardless
+// of whether exceptions are enabled in the component.  Common library code that expects to be used
+// from exception-free components want these concepts, but including <type_traits> directly introduces
+// friction as it requires components not using STL to declare their STL version.  Doing so creates
+// ambiguity around whether STL use is safe in a particular component and implicitly brings in
+// a long list of headers (including <new>) which can create further ambiguity around throwing new
+// support (some routines pulled in may expect it).  Secondarily, pulling in these headers also has
+// the potential to create naming conflicts or other implied dependencies.
+//
+// To promote the use of these core language concepts outside of STL-based binaries, this file is
+// selectively pulling those concepts *directly* from corresponding STL headers.  The corresponding
+// "std::" namespace STL functions and types should be preferred over these in code that is bound to
+// STL.  The implementation and naming of all functions are taken directly from STL, instead using
+// "wistd" (Windows Implementation std) as the namespace.
+//
+// Routines in this namespace should always be considered a reflection of the *current* STL implementation
+// of those routines.  Updates from STL should be taken, but no "bugs" should be fixed here.
+//
+// New, exception-based code should not use this namespace, but instead should prefer the std:: implementation.
+// Only code that is not exception-based and libraries that expect to be utilized across both exception
+// and non-exception based code should utilize this functionality.

+# Default configuration options for tracewpp.
+#
+# This file provides configuration settings for tracewpp. By default, tracewpp
+# uses "defaultwpp.ini" for configuration settings. An alternate INI file can
+# be specified via the -defwpp parameter. Additional configuration settings can
+# be specified via the -ini parameter or via "begin_wpp config" blocks in
+# files specified via the -scan parameter.
+#
+# When parsing an INI file or a "begin_wpp config" block, tracewpp searches for
+# syntax that looks like a function call, e.g. "FunctionName(arg1, ...);". For
+# each function call, if the function name is one of the recognized commands
+# described below (e.g. NOPREFIX, USEPREFIX, INCLUDE), that command is
+# executed. Otherwise, the function call is treated as the definition of a
+# trace function.
+
+################################
+# General configuration commands
+################################
+#
+# FUNC FunctionName(ARG1, ARG2, MSG, ...);
+# FUNC FunctionName{ARG1=value, ARG2=value}(ARG3, ARG4, MSG, ...);
+#
+#   Defines a trace function and its arguments. The tracewpp tool will scan all
+#   source files for calls to the specified trace function. The generated TMH
+#   file will then define the specified name as a macro and will generate code
+#   to handle each call to the macro.
+#
+#   Function definitions are often prefixed by "FUNC", e.g.
+#   "FUNC DoTraceMessage(LEVEL, MSG, ...);". The "FUNC" prefix is optional
+#   but is helpful in drawing attention to function definitions.
+#
+#   Arguments provided in {braces} are defaulted parameters (sometimes called
+#   "assumed arguments"). If you define a trace function
+#   MyTrace{ARG1=5}(MSG, ...), then WPP will treat any use
+#   of MyTrace("...", a, b) as if it were MyTrace(5, "...", a, b), and WPP will
+#   generate macros for MyTrace that include an ARG1 parameter (for use by
+#   user-specified expressions in the macro definition).
+#
+#   Note that when using TMF-based WPP, WPP will expect the user to define
+#   ENABLED and LOGGER macros based on the arguments for defined functions.
+#   For example, if you define a trace function
+#   MyTrace(FLAG, MYARG, MSG, ...), WPP will expect user-defined macros
+#   WPP_FLAG_MYARG_ENABLED(FLAG, MYARG) and WPP_FLAG_MYARG_LOGGER(FLAG, MYARG)
+#   to be provided by the user. These user-supplied macros are usually defined
+#   in terms of the corresponding WPP-supplied macros WPP_LEVEL_ENABLED(LEVEL)
+#   and WPP_LEVEL_LOGGER(LEVEL).
+#
+#   Certain argument names trigger special behavior:
+#   - "MSG" is the format string.
+#   - "..." is a placeholder for the format string arguments. If present, it
+#     must be the last argument.
+#   - "PUBLIC_FILTER" marks the function as conditionally public. The function
+#     will be public if the WPP_PUBLIC_<Flag> macro is defined when the file is
+#     compiled (where <Flag> is the value of the PUBLIC_FILTER argument).
+#
+#   Certain argument names trigger special behavior in manifest-based WPP:
+#   - "ControlGuid" specifies the name of the control GUID for the event. If
+#     there is no ControlGuid argument, tracewpp will determine the control
+#     GUID based on the event's level or keywords.
+#   - "Level" specifies the level of the event. If there is no Level argument,
+#     tracewpp will look for valid level names in all arguments of the event.
+#     If no level name is found, the level will default to "win:Verbose".
+#   - "Keywords" specifies the keywords (flags) of the event. If there is no
+#     Keywords argument, tracewpp will look for valid keyword names in all
+#     arguments of the event. If no keywords are found, the keyword will be
+#     "win:AnyKeyword" (i.e. 0).
+#   - "Name" specifies the event name.
+#   - "Id" allows manual assignment of event Id and Version attributes. Syntax
+#     is either "ID" or "IDvVERSION", e.g. "24" or "24v2". The specified Id
+#     must be a number from 0..65535 that is outside of the auto-assignment
+#     pool. Note that the auto-assignment pool defaults to 10..65535, so manual
+#     assignment generally requires adjusting the auto-assignment pool (via the
+#     TRACERANGE command).
+#   - "Func" specifies the name of the event's call site function. Note that
+#     when using manifest-based WPP, tracewpp is unable to automatically set
+#     the event's function name during manifest generation. The function name
+#     can be manually specified via the Func parameter or it can be included in
+#     the event payload via DEFAULT_FUNC_NAME_IN_EVENT/USE_FUNC_NAME_IN_EVENT.
+#
+# NOPREFIX(FunctionName);
+#
+#   Removes the default trace message prefix "%!STDPREFIX!" for the specified
+#   trace function.
+#
+# USEPREFIX(FunctionName, [Prefix, ArgNames...]);
+# USESUFFIX(FunctionName, [Suffix, ArgNames...]);
+#
+#   Sets the trace message prefix or suffix for the specified trace function.
+#   Each time WPP sees function("message", ...), it will add the specified
+#   prefix or suffix to "message".
+#
+# PUBLIC_FILTER(FunctionName, Flag);
+#
+#   Marks the named function as conditionally public. The function will be
+#   public if the WPP_PUBLIC_<Flag> macro is defined when the file is compiled.
+#   Public functions omit certain metadata from the TMF such as filename and
+#   line number. (Not applicable to manifest-based WPP.)
+#
+# INCLUDE(IniFileName);
+#
+#   Immediately processes the specified file as an INI file.
+#
+# PROCESSFILES(SourceFile...);
+#
+#   Processes the specified input file(s) as if they were specified on the
+#   tracewpp command line. Example: PROCESSFILES("MyFile.cpp", "B*.c");
+#
+# SCANFORMACROS(HeaderFile...);
+#
+#   Scans the specified file(s) as if they were specified with
+#   /scan:HeaderFile on the tracewpp command line.
+#
+# SEPARATE_TRACE_GUID_PER_FILE(Enabled);
+#
+#   If enabled (1), a new trace GUID will be generated for each input file
+#   scanned. This is useful for TMF-based WPP, as it means changes in one
+#   source file will not affect the trace GUID or event IDs of other source
+#   files. This is undesirable for manifest-based WPP, as it requires a
+#   large number of providers to be registered.
+#
+#   This is enabled (1) by default for TMF-based WPP. This is disabled (0) by
+#   default for manifest-based WPP (when the /man parameter is specified).
+#
+# TRACERANGE(Min, Max);
+#
+#   Configures the range of numbers that WPP will use when automatically
+#   assigning event IDs. Default is 10..65535. If manually assigning Ids, you
+#   will need to reduce this range to reserve Ids for manual assignment, e.g.
+#   use TRACERANGE(1000, 65535) so that Ids 1..999 can be manually assigned.
+#
+# WPP_FLAGS(Option...);
+#
+#   Processes the specified options as if they were specified on the tracewpp
+#   command line. Example: WPP_FLAGS(noshrieks, p:MyProject);
+
+################################
+# Type definition commands
+################################
+#
+# The following commands can be used to define data types for use with WPP
+# trace functions. WPP type definitions may include the following settings:
+#
+# - Name: the WPP name of the type being defined. This name must be unique.
+#   When reading the WPP format strings from source code, WPP matches the
+#   requested type against this name. For example, "%d" will cause WPP to look
+#   for a type named "d", and "%!HRESULT!" will cause WPP to look for a type
+#   named "HRESULT".
+# - EquivType: the name of the type in C or C++, e.g. "int". This type will be
+#   used for the parameter of the inline helper function in the generated
+#   code.
+# - MofType: the MOF name of the type (shows up in the TMF file).
+# - FormatSpec: the format string to use for this type in the message string.
+#   For example, if FormatSpec is "I64x" then a message string might look like:
+#   "Value = %10!I64x!".
+# - Sig: the short name to use for this type when generating the names for
+#   helper functions. Two different WPP types might use the same signature
+#   because the types are compatible in terms of the helper functions (the
+#   underlying C/C++ types are the same and the types serialize into ETW data
+#   the same way).
+# - Priority: the priority to give the type during argument sorting (only
+#   significant when the /reorder parameter is used). This value is typically
+#   set to the type's alignment so that more-aligned values sort first and
+#   remain aligned within the ETW data.
+# - ManifestType: describes the how the type should be treated in
+#   manifest-based WPP. The ManifestType is a semicolon-separated list of type
+#   parameters. The first parameter is required and specifies the winmeta input
+#   type, e.g. "win:UInt32" (valid winmeta types are described in winmeta.xml).
+#   Subsequent parameters specify options in the form of a name=value pair. The
+#   supported options are:
+#   - outType: Specifies the winmeta output type (i.e. a type formatting
+#     qualifier), e.g. "xs:string". If not set, the type will not include an
+#     outType attribute in the manifest and will receive default formatting by
+#     the trace decoder. Example use of outType: win:Int32;outType=win:HResult
+#   - adapter: Specifies a function or macro that should be applied to values
+#     of this type before passing the value to the MC-generated EventWrite
+#     macro. For example, if argument a10 has no adapter and argument a11 has
+#     "ADAPT" as its adapter, the MC-generated EventWrite macro would be
+#     invoked as EventWriteMyEvent(a10, ADAPT(a11)). The adapter might perform
+#     a cast (e.g. cast ULONG_PTR to void*) or in the case of a Counted type
+#     might convert a single value into a length+pointer pair. For example, the
+#     adapter for a PUNICODE_STRING type might be the following macro:
+#     #define ADAPT_PSTR(p) p->Length/2, p->Buffer
+#     Example use of adapter: win:CountedUnicodeString;adapter=ADAPT_PSTR
+#
+# CUSTOM_TYPE(Name, BaseType(Extension), [FormatSpec]);
+#
+#   Creates a new type by adding an extension to an existing type. Typically
+#   used to define enumerations, e.g.:
+#   ItemListByte(EnumValues...), ItemListShort(EnumValues...),
+#   ItemListLong(EnumValues...), ItemSetByte(EnumValues...),
+#   ItemSetShort(EnumValues...), ItemSetLong(EnumValues...),
+#   ItemEnum(EnumName), or ItemFlagsEnum(EnumName).
+#
+#   ItemList types are used for list enums, i.e. items counting up from 0.
+#   ItemList types support skipping values via Value=number syntax.
+#
+#   ItemSet types are used for bitset enums, i.e. the first item has value
+#   1, the second has value 2, the third has value 4, the fourth has value 8.
+#
+#   ItemEnum and ItemFlagsEnum types reference the name of a C/C++ enum and
+#   are resolved using symbol information from the PDB. (ItemEnum and
+#   ItemFlagsEnum do not work for manifest-based WPP because the PDB is not
+#   used for resolving enumerations.)
+#
+# TYPEMACRO(Name, BaseType(Extension), [FormatSpec]);
+#
+#   Deprecated. Same as CUSTOM_TYPE.
+#
+# DEFINE_SIMPLE_TYPE(Name, EquivType, MofType, FormatSpec, Sig, Priority,
+#                    [ManifestType]);
+#
+#   Creates a new fixed-length type that is passed to the helper function by
+#   value (uses helper macro WPP_LOGTYPEVAL). Size in the event payload will
+#   be sizeof(EquivType).
+#
+# DEFINE_SIMPLE_TYPE_PTR(Name, EquivType, MofType, FormatSpec, Sig, Priority,
+#                        [ManifestType]);
+#
+#   Creates a new fixed-length type that is passed to the helper function by
+#   address (uses helper macro WPP_LOGTYPEPTR). Size in the event payload will
+#   be sizeof(*value).
+#
+# DEFINE_FLAVOR(Name, BaseType, [MofType, FormatSpec, ManifestType]);
+#
+#   Defines a new type that is based on another similar type, potentially
+#   overriding the base type's MofType, FormatSpec, and manifest type. Omitted
+#   or blank settings will remain the same as the base type.
+#
+# DEFINE_CPLX_TYPE(Name, MacroName, EquivType, MofType, FormatSpec, Sig,
+#                  Priority, [ManifestType]);
+#
+#   Defines a complex type, i.e. one that requires special handling via a
+#   helper macro other than WPP_LOGTYPEVAL or WPP_LOGTYPEPTR. Any type with a
+#   variable length (e.g. any string type) is complex.
+#
+#   MacroName is the name of the helper macro that WPP should invoke when
+#   passing this value to the helper function. The helper macro should itself
+#   invoke the WPP_LOGPAIR macro with the data size and the data pointer. (Note
+#   that helper macros are only used for TMF-based WPP, not for manifest-based
+#   WPP.)
+
+################################
+# Manifest definition commands
+################################
+#
+# The following commands are used with manifest-based WPP. Many of these
+# commands accept a required Name, and allow for an optional Symbol. The item
+# defined by such a command can be referenced by either its name or its
+# symbol. If no symbol is defined, it can only be referenced by its name. The
+# symbol may be useful in cases where the desired name is not a C/C++-friendly
+# identifier.
+#
+# MANIFEST_CONFIGURATION(ManifestFile, [HeaderFile, Prefix]);
+#
+#   For use with manifest-based WPP. Normally specified via the command-line
+#   -man option, not in an INI file or via configuration blocks.
+#
+# MANIFEST_RESOURCES(ResourceFile, [MessageFile, Culture]);
+#
+#   For use with manifest-based WPP. Specifies information about the installed
+#   location of the DLL/EXE/SYS file that contains a manifest's resource data.
+#   If not specified, Culture defaults to "en-us". Since the install location
+#   is usually not known at build time, tracewpp defaults to using dummy paths
+#   for the resource file and message file. The dummy paths are typically
+#   overridden by the /rf and /mf parameters on the wevtutil command line
+#   during manifest installation. Note that the ResourceFile and MessageFile
+#   values must be absolute paths.
+#
+# DEFINE_CONTROL_GUID(Name, [Guid, Symbol]);
+#
+#   For use with manifest-based WPP. Defines a control GUID (aka a provider).
+#   If the Guid parameter is not specified, the GUID for the provider will be
+#   computed by hashing the Name using the same name hashing algorithm as is
+#   used by tracelog, xperf, EventSource, and other ETW tools.
+#
+# DEFINE_BIT(Name, [Mask, Symbol]);
+#
+#   For use with manifest-based WPP. Adds a keyword to the most recently
+#   defined control guid. The default mask of the keyword is the control
+#   guid's lowest unused keyword bit.
+#
+#   Mask may be specified as decimal or hexadecimal and must be a power of 2.
+#
+# DEFINE_KEYWORD(Name, ControlGuidId, Mask, [Symbol]);
+#
+#   For use with manifest-based WPP. Defines a keyword associated with the
+#   specified control GUID. Rarely used: DEFINE_BIT is usually simpler.
+#
+# DEFINE_LEVEL(Name, ControlGuidId, Value, [Symbol]);
+#
+#   For use with manifest-based WPP. Defines a level associated with the
+#   specified control GUID. The level value must not conflict with any
+#   built-in levels (level values 0 through 15 are built-in levels). Rarely
+#   used: the built-in levels are sufficient for most components.
+#
+# DEFINE_BUILTIN_KEYWORD(Name, Mask, [Symbol, Symbol...]);
+#
+#   For use with manifest-based WPP. Normally used in the defaultwpp.ini file,
+#   not in per-project INI files or configuration blocks. Defines a global
+#   (Microsoft-defined) keyword value. These keywords can be used with any
+#   control GUID. These keywords will not be defined in the manifest - they
+#   are expected to match keyword definitions from winmeta.xml.
+#
+# DEFINE_BUILTIN_LEVEL(Name, Value, [Symbol, Symbol...]);
+#
+#   For use with manifest-based WPP. Normally used in the defaultwpp.ini file,
+#   not in per-project INI files or configuration blocks. Defines a global
+#   (Microsoft-defined) level value. These levels can be used with any control
+#   GUID. These levels will not be defined in the manifest - they are expected
+#   to match level definitions from winmeta.xml.
+#
+# DEFAULT_FUNC_NAME_IN_EVENT(Expression, [TypeName]);
+#
+#   For use with manifest-based WPP. When using manifest-based WPP, tracewpp is
+#   unable to automatically set the event's function name during manifest

+#   parameter or it can be included in the event payload via

+
+#   The DEFAULT_FUNC_NAME_IN_EVENT command will add a hidden string property
+#   named "!FUNC!" to every event (except when overridden by
+#   USE_FUNC_NAME_IN_EVENT). The value of the property will be taken from the
+#   specified Expression. The Expression will typically be set to

+#   For use with manifest-based WPP. When using manifest-based WPP, tracewpp is
+#   unable to automatically set the event's function name during manifest
+#   generation. The function name can be manually specified via the Func
+#   parameter or it can be included in the event payload via
+#   DEFAULT_FUNC_NAME_IN_EVENT or USE_FUNC_NAME_IN_EVENT.
+#
+#   The USE_FUNC_NAME_IN_EVENT command with a non-empty value for Expression
+#   will add a hidden string property named "!FUNC!" to every event generated
+#   by the specified trace function. The value of the property will be taken
+#   from the specified Expression. The Expression will typically be set to
+#   "__FUNCTION__". TypeName is the WPP name of the type to use for the hidden
+#   argument. TypeName defaults to "hs" (i.e. nul-terminated char* string).
+#
+#   If Expression is empty (i.e. ""), the "!FUNC!" property will not be added
+#   to events generated by the specified trace function. A blank Expression
+#   can be used to override a default set by DEFAULT_FUNC_NAME_IN_EVENT.

+
+################################
+# Format string syntax
+################################
+#
+# The format string is parsed to determine the type and format of event
+# properties. Format string syntax is similar to printf, i.e. a '%' character
+# not immediately followed by another '%' character will be treated as the
+# start of a property reference.
+#
+# A property reference is parsed as one of the following:
+#
+# '%' [ '{' PropertyName '}' ] [Prefix] ShortTypeName
+# '%' [ '{' PropertyName '}' ] [ArgNum] '!' [Prefix] LongTypeName '!'
+#
+# {PropertyName} is optional. If specified, the name must contain only
+# identifier characters, i.e. a-z, 0-9, and '_'.
+#
+# Prefix includes flags ('-', '+', '#'), width digits, and/or '.' followed by
+# precision digits. Note that prefix does not support "*" or ".*".
+#
+# If prefix is specified, it will be included in the event's format string
+# along with the type's FormatSpec. For example, "%+02hX" would be parsed as
+# Prefix="+02", ShortTypeName="hX". Type "hX" has FormatSpec="X", so the final
+# WPP format string for the property would be "+02X".
+#
+# If the -NoShrieks command-line option is set and the prefix before a
+# ShortTypeName contains only digits, tracewpp will treat the number as an
+# ArgNum instead of a Width.
+#
+# The ArgNum before '!' is optional. It indicates the index of the argument to
+# use for this property reference. If not specified, ArgNum is determined from
+# the position of the property reference in the format string.
+#
+# By default, ShortTypeName is a length (one of "", "I", "I64", "h", "w", "l",
+# or "ll") followed by a specifier (any single character). However, if the
+# -NoShrieks command-line option is set, ShortTypeName is any number of
+# identifier characters (a-z, A-Z, 0-9, '_') and ends at the first
+# non-identifier character.
+#
+# LongTypeName is any non-empty sequence of characters ending at the '!'.
+#
+# ShortTypeName or LongTypeName must match the name of a defined WPP type (i.e.
+# the type names defined below or your own custom types).

+Routine Description:
+
+    This function is the callback WMI calls when we register and when our
+    events are enabled or disabled.
+
+Arguments:
+
+    MinorFunction - specifies the type of callback (register, event enable/disable)
+
+    DataPath - varies depending on the ActionCode
+
+    BufferLength - size of the Buffer parameter
+
+    Buffer - in/out buffer where we read from or write to depending on the type
+        of callback
+
+    Context - the pointer private struct WPP_TRACE_CONTROL_BLOCK
+
+    Size - output parameter to receive the amount of data written into Buffer
+
+Return Value:
+
+    NTSTATUS code indicating success/failure
+
+Comments:
+
+    if return value is STATUS_BUFFER_TOO_SMALL and BufferLength >= 4,
+    then first ulong of buffer contains required size
