Compiler Errors

must specify /c_ext for abstract declarators Abstract declarators represent a Microsoft extension to RPC and are not defined in DCE RPC. Therefore, if your file includes abstract declarators, you cannot compile with the /osf switch, which enforces strict DCE compatibility. MIDL versions 3.0 and later use the /c_ext switch as the default; the /osf switch turns off the /c_ext switch. For information on abstract declarators, see The ACF Body .
