Summary0000092: pthread_mutex_lock return
Description _____________________________________________________________________________
 OBJECTION Enhancement Request Number 22
 gwc:xxxxxxxxxxxxx Defect in XSH pthread_mutex_lock (rdvk# 3)
 [gwc pmtl return] Fri, 9 Jan 2009 15:53:20 +0000
 _____________________________________________________________________________

The RETURN VALUE section on the pthread_mutex_lock() page states:

     "The pthread_mutex_trylock() function shall return zero if a lock
     on the mutex object referenced by mutex is acquired. Otherwise, an
     error number is returned to indicate the error."

 This conflicts with the description of the EOWNERDEAD error for
 pthread_mutex_trylock() which says "The mutex lock shall be acquired
 by the calling thread".
Desired ActionOn line 52739 (1st line of RETURN VALUE) change

     "pthread_mutex_lock() and pthread_mutex_unlock()"

 to

     "pthread_mutex_lock(), pthread_mutex_trylock() and pthread_mutex_unlock()"

 Delete lines 52741-52742 (2nd para of RETURN VALUE).
