pthread_mutex_setname_np(3)
NAME
  pthread_mutex_setname_np - Changes the object name in a mutex object

SYNOPSIS
  #include <pthread.h>

  int pthread_mutex_setname_np(
	  pthread_mutex_t *mutex,
	  const char *name,
	  void *mbz );

LIBRARY
  DECthreads POSIX 1003.1c Library (libpthread.so)

PARAMETERS
  mutex
      Mutex object whose object name is to be changed.

  name
      Object name value to copy into the mutex object.

  mbz Reserved for future use. The value must be zero (0).

DESCRIPTION
  This routine changes the object name in the mutex object specified by mutex
  to the value specified by name. To set a new mutex object's object name,
  call this routine immediately after initializing the mutex 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:

  0   Successful completion.

  [EINVAL]
      The value specified by mutex is invalid, or the length in characters of
      name exceeds 31.

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

ERRORS
  None
