Hello, I was just inspecting libc_r for trying to understand some things and found this: <------------------------- --- src/lib/libc_r/uthread/uthread_cond.c 2002/05/24 04:32:28 1.33 +++ src/lib/libc_r/uthread/uthread_cond.c 2002/11/13 18:13:26 1.34 ... int -_pthread_cond_signal(pthread_cond_t * cond) +__pthread_cond_timedwait(pthread_cond_t *cond, pthread_mutex_t *mutex, + const struct timespec *abstime) +{ + int ret; + + _thread_enter_cancellation_point(); + ret = _pthread_cond_timedwait(cond, mutex, abstime); + _thread_enter_cancellation_point(); + return (ret); +} ----------------------------> Shouldn't that be _thread_leave_cancellation_point() after calling _pthread_cond_timedwait() ? What effect should I see if this is wrong? Best regards, Norbert Koch
