What is the most efficient way to get a relatively precise (say, at least millisecond) time value that is guaranteed to inrease monotonically (even if, say, xntpd adjust the system clock), either portable, or FreeBSD-specific? Is there some user library for using the Pentium performance clock thingy? I have, of course, looked at gettimeofday(2). Is this what I should be using? Does it involve a system call? -Jon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
