Variables
- CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::@26::@27 CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::fence [inherited]
-
Parameters for fence objects
- unsigned int CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::flags [inherited]
-
Only when CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS is used to wait on a CUexternalSemaphore of type CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_NVSCISYNC, the valid flag is CUDA_EXTERNAL_SEMAPHORE_WAIT_SKIP_NVSCIBUF_MEMSYNC which indicates that while waiting for the CUexternalSemaphore, no memory synchronization operations should be performed for any external memory object imported as CU_EXTERNAL_MEMORY_HANDLE_TYPE_NVSCIBUF. For all other types of CUexternalSemaphore, flags must be zero.
- unsigned long long CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::key [inherited]
-
Value of key to acquire the mutex with
- CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::@26::@29 CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::keyedMutex [inherited]
-
Parameters for keyed mutex objects
- CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::@26::@28 CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::nvSciSync [inherited]
-
Pointer to NvSciSyncFence. Valid if CUexternalSemaphoreHandleType is of type CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_NVSCISYNC.
- unsigned int CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::timeoutMs [inherited]
-
Timeout in milliseconds to wait to acquire the mutex
- unsigned long long CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::value [inherited]
-
Value of fence to be waited on
