This is currently achieved +using a fixed timeout of one second. + +The XWin(1) server should indicate somehow (by placing an atom on the root window?) that it is running with it's +internal clipboard integration enabled, and xwinclip should notice this and exit with an appropriate error. + +Probably many other bugs. + +.SH "CONFORMING TO" +ICCCM (Inter-Client Communication Conventions Manual) 2.0 + +.SH AUTHORS +Contributors to xwinclip include Benjamin Riefenstahl, Roland Cassard, Brian Genisio, Colin Harrison, +Harold L Hunt II, Matsuzaki Kensuke, Jon Turney, Chris Twiner and Jeremy Wilkins. -- cgit v1.2.3
