       pthread_rwlock_getname_np  -  Obtain  the object name from a read-write
       lock object

       int pthread_rwlock_getname_np(
	       pthread_rwlock_t *rwlock,

       Address of the read-write lock  object  whose  object  name  is	to  be
       obtained.  Location 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  read-write  lock	object
       specified by rwlock 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  read-write  lock object has not been previously set
       with an object name, this routine copies a C language null string  into
       the buffer 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 rwlock is invalid.
