From e882756311c7b06e59fcc8e582f03852b7dcfd30 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 17 Feb 2011 17:16:20 -0500 Subject: reorganize pthread data structures and move the definitions to alltypes.h this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test. --- src/thread/pthread_mutex_trylock.c | 26 +++++++++++++------------- 1 file changed, 13 insertions(+), 13 deletions(-) (limited to 'src/thread/pthread_mutex_trylock.c') diff --git a/src/thread/pthread_mutex_trylock.c b/src/thread/pthread_mutex_trylock.c index 1e3817bb..29268fdb 100644 --- a/src/thread/pthread_mutex_trylock.c +++ b/src/thread/pthread_mutex_trylock.c @@ -2,27 +2,27 @@ int pthread_mutex_trylock(pthread_mutex_t *m) { - if (m->__type == PTHREAD_MUTEX_RECURSIVE) { + if (m->_m_type == PTHREAD_MUTEX_RECURSIVE) { pthread_t self = pthread_self(); - if (m->__owner == self) { - if ((unsigned)m->__lock >= INT_MAX) return EAGAIN; - a_inc(&m->__lock); + if (m->_m_owner == self->tid) { + if ((unsigned)m->_m_lock >= INT_MAX) return EAGAIN; + a_inc(&m->_m_lock); return 0; } - if (a_fetch_add(&m->__lock, 1)) { - if (a_fetch_add(&m->__lock, -1)==1 && m->__waiters) - __wake(&m->__lock, 1, 0); + if (a_fetch_add(&m->_m_lock, 1)) { + if (a_fetch_add(&m->_m_lock, -1)==1 && m->_m_waiters) + __wake(&m->_m_lock, 1, 0); return EBUSY; } - m->__owner = self; + m->_m_owner = self->tid; return 0; } - if (a_xchg(&m->__lock, 1)) - if (m->__type == PTHREAD_MUTEX_ERRORCHECK - && m->__owner == pthread_self()) return EDEADLK; + if (a_xchg(&m->_m_lock, 1)) + if (m->_m_type == PTHREAD_MUTEX_ERRORCHECK + && m->_m_owner == pthread_self()->tid) return EDEADLK; else return EBUSY; - if (m->__type == PTHREAD_MUTEX_ERRORCHECK) - m->__owner = pthread_self(); + if (m->_m_type == PTHREAD_MUTEX_ERRORCHECK) + m->_m_owner = pthread_self()->tid; return 0; } -- cgit v1.2.1
