Perform other functions while untarring file using "system" command in a C program

[gaf at blu.org (Jerry Feldman)]

Fork() is a Unix system call that spawns a child process which is 
essentialy a clone of the parent.
The exec() system call causes a program (or command) to be executed. The 
wait() system call causes the parent process to wait for the child. In 
contrast, the system() function calls fork() to execute a shell, which then 
executes the command. Check the man pages.
