Subject: Futex manpages out of date
Date: Fri, 15 Jan 2010 08:58:09 -0800 [thread overview]
Message-ID: <4B509EA1.8060509@us.ibm.com> (raw)
The futex man-pages (2,7) from version 3.15-1 and at least a few earlier
versions are considerably out of date with respect to the current
implementation. They don't document newer op codes, such as:
FUTEX_WAIT_BITSET
FUTEX_WAKE_BITSET
FUTEX_WAKE_OP
FUTEX_LOCK_PI
FUTEX_UNLOCK_PI
FUTEX_WAIT_REQUEUE_PI
FUTEX_CMP_REQUEUE_PI
These new wait op codes now use absolute timeouts, while the original
FUTEX_WAIT uses a relative timeout. Lastly, and most importantly, glibc
has removed the futex() wrapper to syscall(SYS_futex, ...). With that in
mind, would people prefer that we simply remove the futex man-pages
(2,7)?
Thanks,
