Oh, well, I proved me wrong. In C++, you can (and should) repeat the typedef struct _Something Something declarations instead of including the full header. But C doesn't like that. It complains about duplicate declarations. Using a common header is effectively the same thing with one difference: You can use a header guard to prevent duplicate declarations. -- Murray Cumming [EMAIL PROTECTED] www.murrayc.com www.openismus.com _______________________________________________ gnome-db-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gnome-db-list
