RTFM :-)
RETURN VALUES
     On success, fork()  returns  0  to  the  child  process  and
     returns  the  process  ID of the child process to the parent
     process.  On failure, fork() returns -1 to the  parent  pro-
     cess, sets errno to indicate the error, and no child process
     is created.

It looks like fork is returning the PID of the child process. Isn't
this what you wanted?
