Hi,
I'm learning GNUstep programming and thought a GNUstep frontend to Xine would
be a relatively easy task for a first application - except one thing, which is
very special about that: Embedding Xine into a GNUstep window.
I do the following to get the information I need for Xine:
// use XGServer dynamically -> no need to link against gnustep-back
Class xgServer = objc_get_class("XGServer");
IMP imp = [xgServer methodForSelector: @selector(_windowWithTag:)];
gswindow_device_t *dev = (gswindow_device_t *)imp(xgServer,
@selector(_windowWithTag:),
[window windowNumber]);
xineVisual.display = dev->display;
xineVisual.screen = dev->screen;
xineVisual.d = dev->ident;
-> is there a cleaner way? I mean, this is now really hacking in the middle of
the internals of the backend... :-/
When I run the program and make Xine display its logo, it appears for a short
time, but then the program segfaults:

Benchmarking memcpy methods (smaller is better):

2003-07-11 18:41:17.185 GSXine[2915] Received an untrapped event
Speicherzugriffsfehler (core dumped)
Any ideas what's going on there? Is my idea realisable at all?
TIA,

no difference, but in practice, there is.
