Variables
- int cudaExternalMemoryHandleDesc::fd [inherited]
 - 
                           
File descriptor referencing the memory object. Valid when type is cudaExternalMemoryHandleTypeOpaqueFd
 - unsigned int cudaExternalMemoryHandleDesc::flags [inherited]
 - 
                           
Flags must either be zero or cudaExternalMemoryDedicated
 - void * cudaExternalMemoryHandleDesc::handle [inherited]
 - 
                           
Valid NT handle. Must be NULL if 'name' is non-NULL
 - const void * cudaExternalMemoryHandleDesc::name [inherited]
 - 
                           
Name of a valid memory object. Must be NULL if 'handle' is non-NULL.
 - const void * cudaExternalMemoryHandleDesc::nvSciBufObject [inherited]
 - 
                           
A handle representing NvSciBuf Object. Valid when type is cudaExternalMemoryHandleTypeNvSciBuf
 - unsigned long long cudaExternalMemoryHandleDesc::size [inherited]
 - 
                           
Size of the memory allocation
 - enumcudaExternalMemoryHandleTypecudaExternalMemoryHandleDesc::type [inherited]
 - 
                           
Type of the handle
 - cudaExternalMemoryHandleDesc::@7::@8 cudaExternalMemoryHandleDesc::win32 [inherited]
 - 
                           
Win32 handle referencing the semaphore object. Valid when type is one of the following:
- 
                                       
cudaExternalMemoryHandleTypeD3D11ResourceKmt Exactly one of 'handle' and 'name' must be non-NULL. If type is one of the following: cudaExternalMemoryHandleTypeOpaqueWin32KmtcudaExternalMemoryHandleTypeD3D11ResourceKmt then 'name' must be NULL.
