Nope.. it need not be the same.. in cases like this: execl("/usr/bin/gzip", "gunzip", NULL); will give you gunzip behavior because the gzip binary looks at argv[0] and changes it's behavior based upon what it finds.. look at crunchgen for the ability to combine different programs into one binary... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not." _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
