The TOG-CUP has no XcupQueryExtension function.
All other functions have a QueryExtension. You
should be able to find out if an extension is
available before trying to use its functions.
[Originally reported as X.Org defect #9440 by the Compaq representative to X.Org]
(Yes, I know XC-MISC is the wrong component, but I didn't see one for TOG-CUP.)
Anyone working on this right now ?
This was still open in the old X.Org bug database, reported against X11R6.5.1 in
2002, but I think it should be closed, since XcupQueryVersion is there in
xc/lib/Xext/Xcup.c and in the TOG-CUP extension spec. You can even see it in
the initial X11R6.4 checkin to the XFree86 CVS, so I don't know why it was
reported as such. I'm closing as "INVALID".
