What compiler is used in that case, BTW, as I get no errors or warnings when compiling a program that includes both stdlib.h (where the official declaration of atexit() is) and gutils.h (without any __cdecl) either with MSVC6 or MSVC8? I hope you aren't using some compiler switch that makes something else than __cdecl the default calling convention for functions without explicitly specified calling convention? Or do the DDK headers do this, but don't pop the default back? The GLib (and GTK+, etc) headers don't specify any calling convention, and things will go horribly wrong if you compile code that calls GLib, GTK+ etc functions with the wrong calling convention. We haven't wanted to uglify the GLib, GTK+, etc headers by adding explicit calling convention decorations for Win32's sake, and nobody has complained so far. --tml _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
