pthread_setname_np

pthread_setname_np(3)					     Library Functions Manual					     pthread_setname_np(3)

NAME

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

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

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

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 routine 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
