/** @file getintegeri_v.c
*
* From the GL_ARB_shader_storage_buffer_object spec:
*
* "To query the starting offset or size of the range of each buffer object
* binding used for shader storage buffers, call GetInteger64i_v with <param>
* set to SHADER_STORAGE_BUFFER_START or SHADER_STORAGE_BUFFER_SIZE
* respectively. <index> must be in the range zero to the value of
* MAX_SHADER_STORAGE_BUFFER_BINDINGS-1. If the parameter (starting offset
* or size) was not specified when the buffer object was bound (e.g. if
* bound with BindBufferBase), or if no buffer object is bound to index, zero
* is returned."
*
* Based on ARB_uniform_buffer_object's getintegeri_v.c
