A mutual exclusion primitive useful for protecting shared data. This mutex will block threads waiting for the lock to become available. The mutex can also be

Description: The pthread_mutex_init () function initializes the given mutex object, using the attributes specified by the mutex attributes object attr. If attr is NULL, then the mutex is initialized with the default attributes (see pthread_mutexattr_init ()). After initialization, the mutex is in an unlocked state.

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. A mutex is initialized in the beginning of the main function. The same mutex is locked in the ‘trythis ()’ function while using the shared resource ‘counter’. At the end of the function ‘trythis ()’ the same mutex is unlocked. At the end of the main function when both the threads are done, the mutex is destroyed.

The object pointed to by mutex is set to an identifier of the newly created mutex. type must have one of the following values: mtx_plain - a simple, non-recursive mutex is created. mtx_timed - a non-recursive mutex, that supports timeout, is created.

Later, ecp_mul_comb calls ecp_drbg_free() which calls mbedtls_ctr_drbg_free() which deletes the mutex, but then ecp_drbg_free() immediately re-creates the mutex using mbedtls_mutex_init(). So when ecp_mul_comb exits there is still a mutex malloc’ed but not free’ed. ecp_mul_comb does return a pointer to the context which contains a pointer to the mutex but I can’t see that anybody deletes

pthread_mutex_init — destroy and initialize a mutex SYNOPSIS top #include int pthread_mutex_init(pthread_mutex_t *restrict mutex , const pthread_mutexattr_t *restrict attr ); pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER; int mtx_init( mtx_t* mutex, int type ); (since C11) Creates a new mutex object with type. The object pointed to by mutex is set to an identifier of the newly created mutex.

If attr is NULL, then the mutex is initialized with the default attributes (see pthread_mutexattr_init () ).
