cudaError_t cudaGraphicsVDPAURegisterVideoSurface	(	struct cudaGraphicsResource **	resource,
		VdpVideoSurface	vdpSurface,
		unsigned int	flags
	)

Registers the VdpVideoSurface specified by vdpSurface for access by CUDA. A handle to the registered object is returned as resource. The surface's intended usage is specified using flags, as follows:

cudaGraphicsMapFlagsNone: Specifies no hints about how this resource will be used. It is therefore assumed that this resource will be read from and written to by CUDA. This is the default value.
cudaGraphicsMapFlagsReadOnly: Specifies that CUDA will not write to this resource.
cudaGraphicsMapFlagsWriteDiscard: Specifies that CUDA will not read from this resource and will write over the entire contents of the resource, so none of the data previously stored in the resource will be preserved.

Parameters:

	resource	- Pointer to the returned object handle
	vdpSurface	- VDPAU object to be registered
	flags	- Map flags

Returns:: cudaSuccess, cudaErrorInvalidDevice, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown

Note:: Note that this function may also return error codes from previous, asynchronous launches.
