cudaError_t cudaD3D9ResourceGetMappedSize	(	size_t *	pSize,
		IDirect3DResource9 *	pResource,
		unsigned int	face,
		unsigned int	level
	)

Deprecated:: This function is deprecated as of Cuda 3.0.

Returns in *pSize the size of the subresource of the mapped Direct3D resource pResource, which corresponds to face and level. The value set in pSize may change every time that pResource is mapped.

If pResource has not been registered for use with CUDA then cudaErrorInvalidResourceHandle is returned. If pResource was not registered with usage flags cudaD3D9RegisterFlagsNone, then cudaErrorInvalidResourceHandle is returned. If pResource is not mapped for access by CUDA then cudaErrorUnknown is returned.

For usage requirements of face and level parameters, see cudaD3D9ResourceGetMappedPointer().

Parameters:

	pSize	- Returned size of subresource
	pResource	- Mapped resource to access
	face	- Face of resource to access
	level	- Level of resource to access

Returns:: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown

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