/**
* \file getprograminterfaceiv.c
*
* Tests the error cases of the GetProgramInterfaceiv interface.
*
* From the GL_ARB_program_interface_query spec:
* "The command
*
* void GetProgramInterfaceiv(uint program, enum programInterface,
* enum pname, int *params);
*
* queries a property of the interface <programInterface> in program
* <program>, returning its value in <params>. The property to return is
* specified by <pname>.
*
* If <pname> is ACTIVE_RESOURCES, the value returned is the number of
* resources in the active resource list for <programInterface>. If the
* list of active resources for <programInterface> is empty, zero is
* returned.
*
* If <pname> is MAX_NAME_LENGTH, the value returned is the length of the
* longest active name string for an active resource in <programInterface>.
* This length includes an extra character for the null terminator. If
* the list of active resources for <programInterface> is empty, zero is
* returned. The error INVALID_OPERATION is generated if
* <programInterface> is ATOMIC_COUNTER_BUFFER, since active atomic counter
* buffer resources are not assigned name strings.
*
* If <pname> is MAX_NUM_ACTIVE_VARIABLES, the value returned is the number
* of active variables belonging to the interface block or atomic counter
* buffer resource in <programInterface> with the most active variables.
* If the list of active resources for <programInterface> is empty, zero is
* returned. The error INVALID_OPERATION is generated if
* <programInterface> is not UNIFORM_BLOCK, ATOMIC_COUNTER_BUFFER, or
* SHADER_STORAGE_BLOCK.
*
* If <pname> is MAX_NUM_COMPATIBLE_SUBROUTINES, the value returned is the
* number of compatible subroutines belonging to the active subroutine
* uniform in <programInterface> with the most compatible subroutines. If
* the list of active resources for <programInterface> is empty, zero is
* returned. The error INVALID_OPERATION is generated unless
* <programInterface> is VERTEX_SUBROUTINE_UNIFORM,
* TESS_CONTROL_SUBROUTINE_UNIFORM, TESS_EVALUATION_SUBROUTINE_UNIFORM,
* GEOMETRY_SUBROUTINE_UNIFORM, FRAGMENT_SUBROUTINE_UNIFORM, or
* COMPUTE_SUBROUTINE_UNIFORM.
*
* [...]
*
* An INVALID_VALUE error is generated by GetProgramInterfaceiv,
* GetProgramResourceIndex, GetProgramResourceName, GetProgramResourceiv,
* GetProgramResourceLocation, and GetProgramResourceLocationIndex if
* <program> is not the name of either a shader or program object.
*
* An INVALID_OPERATION error is generated by GetProgramInterfaceiv,
* GetProgramResourceIndex, GetProgramResourceName, GetProgramResourceiv,
* GetProgramResourceLocation, and GetProgramResourceLocationIndex if
* <program> is the name of a shader object.
*
* INVALID_OPERATION is generated by GetProgramInterfaceiv if the parameter
* <pname> is not supported for the interface <programInterface>."
