Re: Threads/IPC/???
Thanks. i was able to get the script working. g_spawn_async works great. I am now having a problem using the g_spawn_async_with_pipes. The program I am calling works fine as a standalone, but when I spawn it I have trouble with it getting my input. Any hints or progamming examples? The vendor who wrote the program used scanf(%d,cmd); to get the input from the command line, BUT write() sends chars out one byte at a time. Is there a way to keep the scanf in the vendors program?

This should be what you're looking for: http://developer.gnome.org/doc/API/2.0/glib/glib-Spawning-Processes.html#g-spawn-async 2) I need to spawn a task to perform some background operations. i.e. get time from an add in board, arm and disarm an interrupt routine that time tags an external signal -- need to start and stop this on demand. On linux, usually we implement hardware abstraction at the kernel module level, so your interrupt handleing stuff should usually not be in user-space; assuming this is all setup; you can interface with a kernel driver's file desctiptor like any other; check for read/write conditions with GIOChannel/GIOWatch.
