Everything i know on the subject is encoded in gperl_marshal.h and GPerlClosure.xs in the Glib extension. I recall having to do "interesting" work to get the interpreter context set up appropriately to allow callbacks on other threads, but it was almost seven years ago and i couldn't begin to explain it now. http://git.gnome.org/browse/perl-Glib/tree/gperl_marshal.h http://git.gnome.org/browse/perl-Glib/tree/GClosure.xs Specifically, look at GPerlCallback, which is what gtk2-perl uses to wrap the bare functions used as callbacks throughout the gnome api. Things to look for: gperl_callback_invoke(), GPERL_CALLBACK_MARSHAL_INIT(). -- muppet <scott at asofyet dot org>
