[libvirt] [PATCH 02/15] Fix errno handling for pthreads wrappers

* src/util/threads-pthread.c: pthreads APIs do not set errno, instead the return value is the positive errno. Set errno based on the return value in the wrappers --- src/util/threads-pthread.c | 26 +++++++++++++++----------- 1 files changed, 15 insertions(+), 11 deletions(-) diff --git a/src/util/threads-pthread.c b/src/util/threads-pthread.c index 4e00bc5..b3ec06e 100644 --- a/src/util/threads-pthread.c +++ b/src/util/threads-pthread.c @@ -35,8 +35,9 @@ void virThreadOnExit(void) int virMutexInit(virMutexPtr m) { - if (pthread_mutex_init(&m->lock, NULL) != 0) { - errno = EINVAL; + int ret; + if ((ret = pthread_mutex_init(&m->lock, NULL)) != 0) { + errno = ret; return -1; } return 0; @@ -57,11 +58,11 @@ void virMutexUnlock(virMutexPtr m) } - int virCondInit(virCondPtr c) { - if (pthread_cond_init(&c->cond, NULL) != 0) { - errno = EINVAL; + int ret; + if ((ret = pthread_cond_init(&c->cond, NULL)) != 0) { + errno = ret; return -1; } return 0; @@ -69,8 +70,9 @@ int virCondInit(virCondPtr c) int virCondDestroy(virCondPtr c) { - if (pthread_cond_destroy(&c->cond) != 0) { - errno = EINVAL; + int ret; + if ((ret = pthread_cond_destroy(&c->cond)) != 0) { + errno = ret; return -1; } return 0; @@ -78,8 +80,9 @@ int virCondDestroy(virCondPtr c) int virCondWait(virCondPtr c, virMutexPtr m) { - if (pthread_cond_wait(&c->cond, &m->lock) != 0) { - errno = EINVAL; + int ret; + if ((ret = pthread_cond_wait(&c->cond, &m->lock)) != 0) { + errno = ret; return -1; } return 0; @@ -99,8 +102,9 @@ void virCondBroadcast(virCondPtr c) int virThreadLocalInit(virThreadLocalPtr l, virThreadLocalCleanup c) { - if (pthread_key_create(&l->key, c) != 0) { - errno = EINVAL; + int ret; + if ((ret = pthread_key_create(&l->key, c)) != 0) { + errno = ret; return -1; } return 0; -- 1.6.2.5
