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
      Thread object whose object name is to be changed.

  name
      Object name value to copy into the thread object.

  mbz 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:

  0   Successful completion.

  [ESRCH]
      The thread specified by thread does not exist.

  [EINVAL]
      The length in characters of name exceeds 31.

  [ENOMEM]
      Insufficient memory exists to create a copy of the object name string.

ERRORS
  None
