Return Value

The return values of this method are implemented by an application programmer. In general, if no error occurs, program the method to return D3D_OK. Otherwise, program the method to return an appropriate error message from D3DERR or D3DXERR, as this will cause D3DXLoadMeshHierarchyFromX to fail also, and return the error.
