using fork and wait... 1

[GooMooPunch]

What I'm trying to do is have my program make an execlp call and then return back to my original program...

I know that I can use fork to create another process..and that exec will replace the process that it is being called from...but i'm not sure exactly how to use fork and wait and exec together to accomplish this....

It looks something like this

pid_t child;
child = fork();
if ( child == 0 {
  // exec call here
} else
if ( child != -1 ) {
  // child created, now wait for it
  int status;
  waitpid( child, &status, 0 );
} else {
  // some problem, no child
  perror("Fork");
}
