7.29. cudaExternalSemaphoreWaitParams

struct cudaExternalSemaphoreWaitParams

External semaphore wait parameters, compatible with driver type.

Public Members

struct cudaExternalSemaphoreWaitParams::[anonymous]::[anonymous] fence

Parameters for fence objects.

void *fence

Pointer to NvSciSyncFence.

Valid if cudaExternalSemaphoreHandleType is of type cudaExternalSemaphoreHandleTypeNvSciSync.

unsigned int flags

Only when cudaExternalSemaphoreSignalParams is used to signal a cudaExternalSemaphore_t of type cudaExternalSemaphoreHandleTypeNvSciSync, the valid flag is cudaExternalSemaphoreSignalSkipNvSciBufMemSync: which indicates that while waiting for 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.

unsigned long long key

Value of key to acquire the mutex with.

struct cudaExternalSemaphoreWaitParams::[anonymous]::[anonymous] keyedMutex

Parameters for keyed mutex objects.

union cudaExternalSemaphoreWaitParams::[anonymous]::[anonymous] nvSciSync

struct cudaExternalSemaphoreWaitParams::[anonymous] params

unsigned long long reserved

unsigned int reserved[10]

unsigned int timeoutMs

Timeout in milliseconds to wait to acquire the mutex.

unsigned long long value

Value of fence to be waited on.
