Hi Paul, like I've mentioned in my earlier mails, I might be abusing mutexes, so please enlighten me if the following pseudocode example is nutty:
global mutex _mymutex thread 1 (main app calling shared lib funcs): --- lock _mymutex call init function in dll lock _mymutex --- thread 2 (created inside shared lib when init called) do lots of init stuff, like creating a gl context and creating a app wxwidgets main loop unlock _mymutex --- The second lock in thread 1 effectively waits for the created thread to complete initialisation and blocks the main app from calling other functions that depend on the initialisation. regards jp Paul Speed wrote: > > > J.P.
