I am doing an assert if the pthread_mutex_destroy fails. But

Pthread_cond_destroy

do we have a better option compared to assert (apart from raising exception)? EDIT: void cleanUp() { int rval=0; rval = pthread_cond_destroy(&m_Condition); assert(rval == 0); rval = pthread_mutex_destroy(&m_Mutex); assert(rval == 0); rval = pthread_mutexattr_destroy(&m_Attr); assert(rval == 0); } EDIT 2: void semaphoreVMware::semaphoreVMware() { int rval = 0; rval = pthread_mutexattr_init(&m_Attr); assert(rval == 0); rval = pthread_mutexattr_settype(&m_Attr, PTHREAD_MUTEX_RECURSIVE); assert(rval == 0); rval = pthread_mutex_init(&m_Mutex, &m_Attr); assert(rval == 0); rval = pthread_cond_init(&m_Condition, NULL); assert(rval == 0); } EDIT 3:Declaration of the mutex: env::Mutex m_Mutex; c unix pthreads mutex share|improve this question edited Dec 10 '13 at 13:49 alk 45.1k53497 asked Dec 10 '13 at 6:34 Ravikanth 357 do you know why it is failing? –Glenn Teitelbaum Dec 10 '13 at 6:36 Can you please post some sample code?

Pthread_mutex_init Example In C

function shall destroy the mutex object referenced by mutex; the mutex object becomes, in effect, uninitialized. An implementation may cause pthread_mutex_destroy() to set the object http://stackoverflow.com/questions/20487752/how-to-handle-error-conditions-of-pthread-mutex-destroy referenced by mutex to an invalid value. A destroyed mutex object can be reinitialized using pthread_mutex_init(); the results of otherwise referencing the object after it has been destroyed are undefined. It shall be safe to destroy an initialized mutex that is unlocked. Attempting to destroy a locked mutex results https://linux.die.net/man/3/pthread_mutex_destroy in undefined behavior. The pthread_mutex_init() function shall initialize the mutex referenced by mutex with attributes specified by attr. If attr is NULL, the default mutex attributes are used; the effect shall be the same as passing the address of a default mutex attributes object. Upon successful initialization, the state of the mutex becomes initialized and unlocked. Only mutex itself may be used for performing synchronization. The result of referring to copies of mutex in calls to pthread_mutex_lock(), pthread_mutex_trylock(), pthread_mutex_unlock(), and pthread_mutex_destroy() is undefined. Attempting to initialize an already initialized mutex results in undefined behavior. In cases where default mutex attributes are appropriate, the macro PTHREAD_MUTEX_INITIALIZER can be used to initialize mutexes that are statically allocated. The effect shall be equivalent to dynamic initialization by a call to pthread_mutex_init() with parameter attr specified as NULL, except that no error checks are performed. Return Value If successfu

Programmer's ManualPTHREAD_MUTEX_DESTROY(3P) PROLOG top This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. NAME top pthread_mutex_destroy, pthread_mutex_init — destroy and initialize a mutex SYNOPSIS top #include int pthread_mutex_destroy(pthread_mutex_t *mutex); int pthread_mutex_init(pthread_mutex_t *restrict mutex, const pthread_mutexattr_t *restrict attr); pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER; DESCRIPTION top The pthread_mutex_destroy() function shall destroy the mutex object referenced by mutex; the mutex object becomes, in effect, uninitialized. An implementation may cause pthread_mutex_destroy() to set the object referenced by mutex to an invalid value. A destroyed mutex object can be reinitialized using pthread_mutex_init(); the results of otherwise referencing the object after it has been destroyed are undefined. It shall be safe to destroy an initialized mutex that is unlocked. Attempting to destroy a locked mutex or a mutex that is referenced (for example, while being used in a pthread_cond_timedwait() or pthread_cond_wait()) by another thread results in undefined behavior. The pthread_mutex_init() function shall initialize the mutex referenced by mutex with attributes specified by attr. If attr is NULL, the default mutex attributes are used; the effect shall be the same as passing the address of a default mutex attributes object. Upon successful initialization, the state of the mutex becomes initialized and unlocked. Only mutex itself may be used for performing synchronization. The result of referring to copies of mutex in calls to pthread_mutex_lock(), pthread_mutex_trylock(), pthread_mutex_unlock(), and pthread_mutex_destroy() is undefined.

In cases where default mutex attributes are appropriate, the macro PTHREAD_MUTEX_INITIALIZER can be used to initialize mutexes. The effect shall be equivalent to dynamic initialization by a call to pthread_mutex_init() with parameter attr specified as NULL, except that no error checks are performed. The behavior is undefined if the value specified by the mutex argument to pthread_mutex_destroy() does not refer to an initialized mutex. The behavior is undefined if the value specified by the attr argument to pthread_mutex_init() does not refer to an initialized mutex attributes object. RETURN VA
