[lwip-devel] [bug #20842] unix sys_arch_protect faulty

[Frédéric Bernon]

Follow-up Comment #3, bug #20842 (project lwip):

If the mutex was created with PTHREAD_MUTEX_RECURSIVE attribute with a
pthread_mutex_init, I think it will be better than using the macro
PTHREAD_MUTEX_INITIALIZER. In this case, you could have :

sys_prot_t sys_arch_protect(void)
{ return pthread_mutex_lock(&lwprot_mutex);
}

Or even a define...
