Does POSIX define what happens when a pthread currently holding a mutex
locks the same mutex?

i.e.

void f()
{
pthread_mutex_lock(&some_mutex);
pthread_mutex_lock(&some_mutex);

}

The Linux (MDK9.1) implementation of pthreads has a non-portable mutex
attribute letting you specify what behavior you want in said situation.

I'd like to try to write portable code, though.
