Hye there.
There previously has been a discussion about forking a child using Xforms.
I'm trying to get that to work as well. I've looked in my archives, and found
the talk about the mpeg/tv solution. I'mn doing the same thing:
pipe();fork(), dup(), etc.
The child starts up '/usr/sbin/sar', and parent has to read output from child
to make plots etc.
Now Steve mentioned something about the 'horrible async error', but what's that
exactly?
Whenever my program forks, at every X-event I get an error like:
Xlib: Reply sequence number (0x2e9)
exceeds request sequence number(0x2e8)
in reply type 0x1!
And I mean every! (motion/press/release/enter/leave)
Steve also said to
"Yes, if you confine the interaction between the program and XForms to
only one process -- multiple processes trying to talk to the server
over the same descriptor will cause the dreaded "Xlib async error"."
How to confine this?
Bye, Marco
