unsigned long long  value

Variables

void * cudaExternalSemaphoreSignalParams::fence [inherited]

Pointer to NvSciSyncFence. Valid if cudaExternalSemaphoreHandleType is of type cudaExternalSemaphoreHandleTypeNvSciSync.

cudaExternalSemaphoreSignalParams::@11::@12 cudaExternalSemaphoreSignalParams::fence [inherited]

Parameters for fence objects

unsigned int cudaExternalSemaphoreSignalParams::flags [inherited]

Only when cudaExternalSemaphoreSignalParams is used to signal a cudaExternalSemaphore_t of type cudaExternalSemaphoreHandleTypeNvSciSync, the valid flag is cudaExternalSemaphoreSignalSkipNvSciBufMemSync: which indicates that while signaling the cudaExternalSemaphore_t, no memory synchronization operations should be performed for any external memory object imported as cudaExternalMemoryHandleTypeNvSciBuf. For all other types of cudaExternalSemaphore_t, flags must be zero.

cudaExternalSemaphoreSignalParams::@11::@14 cudaExternalSemaphoreSignalParams::keyedMutex [inherited]

Parameters for keyed mutex objects

unsigned long long cudaExternalSemaphoreSignalParams::value [inherited]

Value of fence to be signaled
