Variables

void * CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS_v1::fence [inherited]

Pointer to NvSciSyncFence. Valid if CUexternalSemaphoreHandleType is of type CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_NVSCISYNC.

CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS_v1::@19::@20 CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS_v1::fence [inherited]

Parameters for fence objects

unsigned int CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS_v1::flags [inherited]

Only when CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS is used to signal a CUexternalSemaphore of type CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_NVSCISYNC, the valid flag is CUDA_EXTERNAL_SEMAPHORE_SIGNAL_SKIP_NVSCIBUF_MEMSYNC which indicates that while signaling 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_SIGNAL_PARAMS_v1::key [inherited]

Value of key to release the mutex with

CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS_v1::@19::@22 CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS_v1::keyedMutex [inherited]

Parameters for keyed mutex objects

unsigned long long CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS_v1::value [inherited]

Value of fence to be signaled
