pthread_setname_np(3)					 pthread_setname_np(3)

NAME
       pthread_setname_np  -  Changes the object name in the thread object for
       an existing thread

SYNOPSIS
       #include <pthread.h>

       int pthread_setname_np(
	       pthread_thread_t thread,
	       const char *name,
	       void *mbz );

LIBRARY
       DECthreads POSIX 1003.1c Library (libpthread.so)

PARAMETERS
       Thread object whose object name is to be changed.  Object name value to
       copy  into  the thread object.  Reserved for future use. The value must
       be zero (0).

DESCRIPTION
       This routine changes the object name in the thread object specified  by
       thread  to  the	value  specified by name.  To set an existing thread's
       object name, call this routine after creating the thread. However, with
       this  approach  your  program must account for the possibility that the
       target thread has already exited or has been canceled before this  rou‐
       tine is called.

       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.

       This routine contrasts with pthread_attr_setname_np, which changes  the
       object  name  attribute	in  a thread attributes object that is used to
       create a new thread.

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 thread specified by thread does not	exist.
       The  length  in	characters  of	name  exceeds 31.  Insufficient memory
       exists to create a copy of the object name string.

ERRORS
       None
