Subj : Using a JSDebugErrorHook To : netscape.public.mozilla.jseng From : Sterling Bates Date : Tue Jun 15 2004 02:13 pm I just need to make sure that the calling convention for this callback is the same as all other callbacks. When my debug hook is called I get an access violation on the very first line: add cl,[ebx-$073b7c14] It doesn't help me much, but I assume it has to do with the cdecl calling type. I've checked the parameters and they look OK. If more info is needed I'll be happy to try and find what's required. Thanks, Sterling .
