I never did either. But as far as I know does longjmp does rewind the stack
direkt after the setjmp call. It's like rewinding everything you did last day
and wake up again :)
xwinclip might look like this
init
SetIOErrorHandler
setjmp
XOpenDisplay <----------------------+
while (true) |
XNextEvent |
| processEvent |
| |
|(on error) |
+---> IOErrorHandler |
CloseConnection |
longjmp ------------+
To integrate it into the server, you would have to create a new thread/
process at server statup and start in the diagram at "init"
