External semaphore handle descriptor.

Public Members

CUexternalSemaphoreHandleType type

Type of the handle.

int fd

File descriptor referencing the semaphore object.

Valid when type is one of the following:

• CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_OPAQUE_FD

• CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_TIMELINE_SEMAPHORE_FD

void *handle

Valid NT handle.

Must be NULL if ‘name’ is non-NULL

const void *name

Name of a valid synchronization primitive.

Must be NULL if ‘handle’ is non-NULL.

struct CUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC_v1::[anonymous]::[anonymous] win32

Win32 handle referencing the semaphore object.

Valid when type is one of the following:

• CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_OPAQUE_WIN32

• CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_OPAQUE_WIN32_KMT

• CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_D3D12_FENCE
