+      *              pointer to an instance of pthread_mutexattr_t
+      *
+      *      pshared

+      *      Mutexes creatd with 'attr' can be shared between
+      *      processes if pthread_mutex_t variable is allocated
+      *      in memory shared by these processes.

+      *      NOTES:
+      *              1)      pshared mutexes MUST be allocated in shared
+      *                      memory.
+      *
+      *              2)      The following macro is defined if shared mutexes
+      *                      are supported:
+      *                              _POSIX_THREAD_PROCESS_SHARED
+      *
+      * RESULTS
+      *              0               successfully set attribute,
+      *              EINVAL          'attr' or pshared is invalid,
