pthread_rwlock_setname_np(3)			  pthread_rwlock_setname_np(3)

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

SYNOPSIS
       #include <pthread.h>

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

LIBRARY
       DECthreads POSIX 1003.1c Library (libpthread.so)

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
