waitpid PID,FLAGS
Waits for a particular child process to terminate and returns the pid of the deceased process, or -1 if there is no such child process.

(Also, note that the flag 0 indicates a blocking wait. On systems that support it the WNOHANG flag causes an immediate return if the child pid is not dead.)
