New subject: [Spam] Re: State of the WIDL

22 Feb 2005

Hi all,
there is some good news to tell about WIDL. It is able to build the
header file, client stub file and server stub file for _very_ simple rpc
applications. I got a slightly modified version of the hello example
from MSDN working.
There are still a lot of features missing from WIDL but it is able to
create stubs for simple functions that don't take any arguments and
return no or basic type values. Returning pointers is not supported yet.
So, supported functions look like that:
        void My1stRpcFunc(void);
        int My2ndRpcFunc(void);
        unsingned long My3rdRpcFunc(void);
Another restriction is the handling of implicit binding handles. These
binding handles are usually declared in an ACF file. But since ACF files
are not supported yet the declaration must take place in the IDL file.
MIDL supports this as well if you use the '/app_config' option.
Explicit binding handles are not supported yet.
Finally, WIDL does not support MIDLs '/oldnames' option. This option is
used to enable the old naming conventions for interface handles. This is
a minor issue because the MSDN examples use the old naming conventions.
Next, I want to implement support for basic type function arguments.
The whole source code to WIDL is published under the LGPL so feel free
to contribute it to WINE.

Eric
