The values used in LINT are usually and intentionally *not* the default values. The reason for this is to try to make sure that you get at least some testing with non-default values. To find the actual default values used I suggest you look in the code. (The actual .c/.h files that is. LINT is not the code.) The comments in LINT are probably correct though. -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
