-
cuvsError_t cuvsStreamSet(cuvsResources_t res, cudaStream_t stream)#
Set cudaStream_t on cuvsResources_t to queue CUDA kernels on APIs that accept a cuvsResources_t handle.
- Parameters:
res – [in] cuvsResources_t opaque C handle
stream – [in] cudaStream_t stream to queue CUDA kernels

stream – [out] cudaStream_t stream to queue CUDA kernels
- Returns:
cuvsError_t
-
cuvsError_t cuvsStreamSync(cuvsResources_t res)#
Syncs the current CUDA stream on the resources object.
- Parameters:
res – [in] cuvsResources_t opaque C handle

Error Handling#
-
enum cuvsError_t#
An enum denoting return values for function calls.
Values:
-
enumerator CUVS_ERROR#
-
enumerator CUVS_SUCCESS#
-
enumerator CUVS_ERROR#
-
const char *cuvsGetLastErrorText()#
Returns a string describing the last seen error on this thread, or NULL if the last function succeeded.
-
void cuvsSetLastErrorText(const char *error)#
Sets a string describing an error seen on the thread. Passing NULL clears any previously seen error message.
