变量
- void * cudaExternalSemaphoreWaitParams_v1::fence [inherited]
-
指向NvSciSyncFence的指针。当cudaExternalSemaphoreHandleType的类型为cudaExternalSemaphoreHandleTypeNvSciSync时有效。
- cudaExternalSemaphoreWaitParams_v1::@18::@19 cudaExternalSemaphoreWaitParams_v1::fence [inherited]
-
栅栏对象的参数
- unsigned int cudaExternalSemaphoreWaitParams_v1::flags [inherited]
-
仅当使用cudaExternalSemaphoreSignalParams来触发类型为cudaExternalSemaphoreHandleTypeNvSciSync的cudaExternalSemaphore_t时，有效标志为cudaExternalSemaphoreSignalSkipNvSciBufMemSync：这表示在等待cudaExternalSemaphore_t期间，不应为任何以cudaExternalMemoryHandleTypeNvSciBuf形式导入的外部内存对象执行内存同步操作。对于所有其他类型的cudaExternalSemaphore_t，标志必须为零。
- unsigned long long cudaExternalSemaphoreWaitParams_v1::key [inherited]
-
获取互斥锁所需的键值
- cudaExternalSemaphoreWaitParams_v1::@18::@21 cudaExternalSemaphoreWaitParams_v1::keyedMutex [inherited]
-
键控互斥对象的参数
- unsigned int cudaExternalSemaphoreWaitParams_v1::timeoutMs [inherited]
-
等待获取互斥锁的超时时间（毫秒）
- unsigned long long cudaExternalSemaphoreWaitParams_v1::value [inherited]
-
需要等待的围栏值
