Non-blocking version of system()

Question

I want to launch a process from within my c program, but I don\'t want to wait for that program to finish. I can launch that process OK using system() but that always waits.

Answer 1

Why not use fork() and exec(), and simply don't call waitpid()?

For example, you could do the following:

// ... your app code goes here ...
pid = fork();
if( pid < 0 )
    // error out here!
if( !pid && execvp( /* process name, args, etc. */ )
    // error in the child proc here!
// ...parent execution continues here...
