pthread_getname_np(3)
NAME
  pthread_getname_np - Obtain the object name from the thread object of an
  existing thread

SYNOPSIS
  #include <pthread.h>

  int pthread_getname_np(
	  pthread_thread_t thread,
	  char *name,
	  size_t len );

LIBRARY
  DECthreads POSIX 1003.1c Library (libpthread.so)

PARAMETERS
  thread
      Thread object whose object name is to be obtained.

  name
      Location to store the obtained object name.

  len Length in bytes of buffer at the location specified by name.

DESCRIPTION
  This routine copies the object name from the thread object specified by
  thread to the buffer at the location name.  Before calling this routine,
  your program must allocate the buffer indicated by name.

  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.

  If the specified thread object has not been previously set with an object
  name, this routine copies a C language null string into the buffer at
  location name.

  This routine contrasts with pthread_attr_getname_np, which obtains 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.

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

ERRORS
  None
