Description

The platform independent function httplib_pthread_mutex_lock() is used to lock a mutex. The function returns 0 if this is succesful, or an error code if it fails. If a mutex is locked by another thread, the function will not return but wait until the other thread releases the mutex and the mutex be successfully locked. On systems which support it, this function is implemented as a direct call to pthread_mutex_lock(). On other systems own code is used to emulate the same functionality.
