This is a question for the real programmer so please dig in!!!
My problem is as follows:
I have a program with two buttons: Enter & Reset (Alfaskop keys!).
When I press the Enter button I send something to a mainframe and
expect and answer back - but it may take minutes! That's why the
Reset button was implemented - but to get the notifier to dispatch
the Reset callback routine the Send callback routine has to return
to the notifier - i.e. it is not busy anymore!
NOTE 1: We use notify_set_input_func & notify_set_itimer_func to
implement a time out functionality and it seems to work.
My question is as follows:
May I use a notify_dispatch loop in the Enter callback function
to dispatch the Reset callback function if the user presses the
button? How should I write it (when considering NOTE 1)? I create
a CPU consuming loop if I write (Explicit dispatching):
XFlush(dpy);
while (!reset_pressed)
{
notify_dispatch();
XFlush(dpy);
/* I have _no_ code to put here - stolen from p.400 */
}
NOTE 2: I'm not able to use implicit dispatching because I'm not
using the standard read() even though I have a file desc.
for notify_set_input_func and it wouldn't help me because

NOTE 3: I will not use a notice box as long as they grab the whole
screen. Because there is other applications running.

Is there a way to block the callback routine if there is nothing
to dispatch?!?

using the standard read() even though I have a file desc.
