NAME
       pthread_rwlock_setname_np - Changes the object name in a read-write lock object.

LIBRARY
       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS
       #include <pthread.h>

       int   pthread_rwlock_setname_np(
			     pthread_rwlock_t	       *rwlock,
			     const char 	       *name,
			     void		       *mbz);

PARAMETERS
       Read-write lock object whose object name is to be changed.  Object name value to copy into the read-write lock object.  Reserved for future
       use. The value must be zero (0).

DESCRIPTION
       This routine changes the object name in the read-write lock object specified by rwlock to the value specified by name. To set a	new  read-
       write lock object's object name, call this routine immediately after initializing the read-write lock object.

       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 31.

RETURN VALUES
       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, or the length in characters of name exceeds 31.  Insufficient memory
       exists to create a copy of the object name string.

ERRORS
       None
