You should check your man page and you should see somrthing
like...
ERRORS
The pthread_mutex_lock function returns the following
error code on error:
EINVAL the mutex has not been properly initialized.
EDEADLK
the mutex is already locked by the calling
thread (``error checking'' mutexes only).
As defined in the errno.h file...
#define EINVAL 22 /* Invalid argument */

I'm not exactly clear on your question.
In AIX 4.3, the mutex "attributes" are not used.
Therefore, you can probably just use the default
initialization... pthread_mutex_init(&mymutex, NULL)
You must call this prior to using that mutex. You should
NOT attempt to re-init the same mutex more than once
unless interleaved by a call to pthread_mutex_destroy.
So if I understand your question correctly, my answer
would be "synchronous".
