Fork and exec are the traditional way of doing this sort of thing.

You can call system() to run another program as well, but you will have to wait for the second command to finish.

Dependent on what you need vfork might be best since you intend to run a completely different program and probably don't need to retain the process space of the parent program.

man on any of these for more info.

I highly recommend you pick up a copy of Stevens' Advanced Programming in the UNIX Environment.

It's the standard reference for all the "system" programming tasks, like fork and exec. It also covers threads, sockets, IPC, pseudo-terminals, etc.
