From 3f56b7f65adb9ee35cd0f878ca00b92011eec427 Mon Sep 17 00:00:00 2001 From: David 'Digit' Turner Date: Tue, 22 Sep 2009 12:40:22 -0700 Subject: Add pthread_mutex_lock_timeout_np This is used to perform a mutex lock for a given amount of milliseconds before giving up. Using the _np prefix since this is absolutely not portable. Also remove a compiler warning in pthread_attr_getstackaddr --- libc/include/pthread.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'libc/include') diff --git a/libc/include/pthread.h b/libc/include/pthread.h index ae7b758..6603b3f 100644 --- a/libc/include/pthread.h +++ b/libc/include/pthread.h @@ -207,6 +207,13 @@ int pthread_cond_timeout_np(pthread_cond_t *cond, pthread_mutex_t * mutex, unsigned msecs); +/* same as pthread_mutex_lock(), but will wait up to 'msecs' milli-seconds + * before returning. same return values than pthread_mutex_trylock though, i.e. + * returns EBUSY if the lock could not be acquired after the timeout + * expired. + */ +int pthread_mutex_lock_timeout_np(pthread_mutex_t *mutex, unsigned msecs); + int pthread_key_create(pthread_key_t *key, void (*destructor_function)(void *)); int pthread_key_delete (pthread_key_t); int pthread_setspecific(pthread_key_t key, const void *value); -- cgit v1.1
