AllocatePhysicalScanSpaceICMedia
This function reserves the physical memory for a single image. It does not matter to the driver how physical memory is handled
on the specific platform. When the "pseudo-handle" is passed to various functions, a specific block of physical memory is
referenced.
DWORD AllocatePhysicalScanSpaceICMedia(
void
)
Returns
DWORD - a "pseudo-handle" to physical memory on success. This "pseudo-handle" will be used to communicate a
specific physical buffer when other memory functions are called. This function returns zero on failure.
