       pthread_mutex_getname_np - Obtain the object name from a mutex object

       Address of the mutex object whose object name is to be obtained.	 Loca‐
       tion to store the obtained object name.	Length in bytes of  buffer  at
       the location specified by name.

       This  routine copies the object name from the mutex object specified by
       mutex to the buffer at the location name.  Before calling this routine,
       your program must allocate the buffer indicated by name.

       The  object name is a C language string and provides an identifier that
       is meaningful to a person debugging  a  DECthreads-based	 multithreaded
       application.   The  maximum  number of characters in the object name is

       If the specified mutex object has  not  been  previously	 set  with  an
       object name, this routine copies a C language null string into the buf‐
       fer at location name.

       If an error condition occurs, this routine  returns  an	integer	 value
       indicating  the	type  of error. Possible return values are as follows:
       Successful completion.  The value specified by mutex is invalid.
