[Mono-devel-list] Unions in C#, and the Bug# 58798 in GDA

I found that Gtk# use a series of perl script as well as C# program
called CodeGenerator, to auto-generate C# code from the sources.
In the case of Gda#, theres a definition of a fundamental type called
GdaValue, wich in his definition has a union (like in GValue struct),
but the parser and CodeGenerator, don't have support to generate a C#
representative of a union.
You know, in C# doesn't exist unions, but you can use the FieldOffset
attribute at cero, to have a in memory representation of a union. The
actual definition of GdaValue and "correct" code representation in C#
can be found the report and comments of the bug# 58798.
The the parser (a perl script called gapi-parser and the sub scripts,
specialy the api2xml) need generate a correcto XML file representation
for a union, and need be modified the C# code for CodeGenerator to
I'll try to help in any form, but I'm not a expert in perl or C#; but
I think it's very important to have Gda# working in Mono.
