Re: OT: How to call unix shell scripts from 'C'?

If you want the "C" program and the spawned shell script to "interact" and communicate back and forth with each other, then you'd have to use the "pipe()" system call to set up a two-way interprocess-communication pipe in the "C" program, then call "fork()" to spawn a new identical process (including the IPC pipes), then finally "exec()" in the child process to bring the image of the desired shell running it's shell script in. Of course, each port of "C" has variations on those basic function call (i.e. "exec()" can be "execv()", "execve()", "execle()", etc).

If you're just going to have the "C" program spawn the shell script that will operate independently of its parent, you can just call the "system()" library call and be done with it...

Hope this helps...
