From ec381af90208a5675183202cf05078eac208edfb Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Tue, 2 Aug 2011 21:11:36 -0400 Subject: unify and overhaul timed futex waits new features: - FUTEX_WAIT_BITSET op will be used for timed waits if available. this saves a call to clock_gettime. - error checking for the timespec struct is now inside __timedwait so it doesn't need to be duplicated everywhere. cond_timedwait still needs to duplicate it to avoid unlocking the mutex, though. - pushing and popping the cancellation handler is delegated to __timedwait, and cancellable/non-cancellable waits are unified. --- src/thread/pthread_rwlock_timedwrlock.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/thread/pthread_rwlock_timedwrlock.c') diff --git a/src/thread/pthread_rwlock_timedwrlock.c b/src/thread/pthread_rwlock_timedwrlock.c index 96827749..484808e8 100644 --- a/src/thread/pthread_rwlock_timedwrlock.c +++ b/src/thread/pthread_rwlock_timedwrlock.c @@ -7,7 +7,7 @@ int pthread_rwlock_timedwrlock(pthread_rwlock_t *rw, const struct timespec *at) if (!w) a_inc(&rw->_rw_waiters), w++; if ((nr=rw->_rw_readers)) p = &rw->_rw_readers; else nr=1, p = &rw->_rw_wrlock; - if (__timedwait(p, nr, CLOCK_REALTIME, at, 0)==ETIMEDOUT) { + if (__timedwait(p, nr, CLOCK_REALTIME, at, 0, 0, 0)==ETIMEDOUT) { if (w) a_dec(&rw->_rw_waiters); return ETIMEDOUT; } -- cgit v1.2.1
