Dear Xorg :
Something I had not thought of came up today. Could multiple threads
call XDrawPoint() and then XFlush() ? Suppose sixteen threads are
dispatched to do some foo and each of them utters some XDrawPoint()
calls and then XFlush()? Is that remotely thread safe?
Sorry, assume XInitThreads() is in place. Am I stuck with using
XLockDisplay() and XUnlockDisplay() and really multiple threads can
not really do work simultaneously. That is the question.
xinitthreads should make anything in xlib "mt safe"..
OKay .. good enough for me .. for now at least.
but ... how can you sensibly have 2 threads draw to the same target in any
way ... unless you very specifically avoid ever overdrawing ...
Exactly that way.
Dennis
