I
think that you should do that in a second thread and leave the iup.MainLoop
working free. This should also reduce processor usage. Best, scuri From: lua-bounces@bazar2.conectiva.com.br
[mailto:lua-bounces@bazar2.conectiva.com.br] On Behalf Of Bob Hibberdine Hi all, I have an Lua / IUP
script that runs other scripts which in turn run external programs. This is all
running with Lua For Windows. I use io.popen to
start any external [program and wait in a loop for an EOF from the output
pipe. Within this loop I call iup.flush{} to keep the parent Windows GUI app
“alive” This all works fine
for as long as there is output from the external program. If not, the read from
the pipe blocks (until the program ends) and my Windows GUI freezes. Is there a simple way
around this without using specialist libraries etc? Can you do non-blocking
IO with standard Lua? Many Thanks, Bob
