kStatus kCudaStream_SetDefaultSync	(	kCudaStream	stream,
		kCudaSync	sync
	)

Sets the default synchronization mode of the stream.

The default stream synchronization mode determines how operations are performed when a synchronization mode is not otherwise specified as an explicit argument to an operation (e.g., kObject_Clone). This setting only applies to kApi/kFireSync utility methods; the underlying Cuda runtime library does not support a default synchronization mode setting.

If this method is not called, the stream's default synchronization mode will be kCUDA_SYNC_WAIT_HOST.

Parameters

stream	Cuda stream.
sync	Default synchronization mode.

Returns

Operation status.
