PTHREAD_MUTEX_INITIALIZER vs pthread_mutex_init ( &mutex, param)

Question

Is there any difference between

pthread_mutex_t lock = PTHREAD_MUTEX_INITIALIZER;

Or

pthread_mutex_t lock         


        

Answer 1

You can set more attributes of the mutex with the dynamic initialisation, plus you can only use the dynamic method if you're adding a bunch of mutexes at run time.

There's nothing wrong with the static approach though, if that fits your needs.
