Currently, clock_gettime syscall does not implement CLOCK_VIRTUAL as described in clock_gettime(2). EINVAL is returned. Either a BUGS section should be added to clock_gettime(2) to indicate that a described feature is not present, or the implementation should be fixed. >How-To-Repeat: struct timespec ts; if (clock_gettime(CLOCK_VIRTUAL, &ts) != 0) { perror("clock_gettime"); exit(-1); } >Fix: Described in description. I have not written up patches. Presumably a fix would require maintaining state in the proc structure -- this would be inefficient in many ways as most processes don't use realtime clock data about themselves. Maintaining the accuracy of a lot of clocks is presumably far less easy than maintaining it for a few. >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
