ulFlags (ULONG)
This flag has the following values:
ENDIVE_REQUEST_UNAVAILABLE
If the integrity of the off-screen VRAM memory cannot be guaranteed for any reason, the contents will be copied into globally shared system memory (pSysMem) and the ENDIVE_REQUEST_RELOCATED bit will be set.
If integrity can be guaranteed later on, contents will be relocated (copied back) to off-screen VRAM from system memory and this bit will be set again (pSysMem will be NULL).
