You must first cast arg to an int pointer, and then dereference it (and assign its value to `fd'). -- +-------------------+---------------------------------------------------+ | Chris Costello | CCITT - Can't Conceive Intelligent Thoughts Today | | chris@FreeBSD.org | | +-------------------+---------------------------------------------------+ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
