Variables
- int CUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC_v1::fd [inherited]
-
File descriptor referencing the semaphore object. Valid when type is one of the following:
- unsigned int CUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC_v1::flags [inherited]
-
Flags reserved for the future. Must be zero.
- void * CUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC_v1::handle [inherited]
-
Valid NT handle. Must be NULL if 'name' is non-NULL
- const void * CUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC_v1::name [inherited]
-
Name of a valid synchronization primitive. Must be NULL if 'handle' is non-NULL.
- const void * CUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC_v1::nvSciSyncObj [inherited]
-
Valid NvSciSyncObj. Must be non NULL
- CUexternalSemaphoreHandleTypeCUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC_v1::type [inherited]
-
Type of the handle
- CUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC_v1::@20::@21 CUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC_v1::win32 [inherited]
-
Win32 handle referencing the semaphore object. Valid when type is one of the following:
-
CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_TIMELINE_SEMAPHORE_WIN32 Exactly one of 'handle' and 'name' must be non-NULL. If type is one of the following:
-
CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_D3D11_KEYED_MUTEX_KMT then 'name' must be NULL.
