/ms_ext

midl /ms_ext

Effective with MIDL version 3.0, the features enabled by this switch are now the default mode for the MIDL compiler. Using the switch will not generate a compiler error, so you do not have to remove references to /ms_ext or /c_ext from an existing makefile.

The following Microsoft extensions to OSF DCE are now available by default:

• Interface definitions for OLE objects. For more information on the files generated for OLE interfaces, see Files Generated for a COM Interface.
• A callback attribute specifying a static callback function on the client.
• cpp_quote(quoted_string) and #pragma midl_echo
• wchar_t wide-character types, constants, and strings
• enum initialization (sparse enumerators)
• Expressions as size and discriminator specifiers.
• Handle extensions.
• Pointer-attribute type inheritance.
• Multiple interfaces.
• Definitions outside of the interface block.
• You can omit directional attributes (in, out).
