pthread_key_setname_np(3)


NAME

  pthread_key_setname_np - Change the object name in a thread-specific data
  key object


SYNOPSIS

  #include <pthread.h>

  int pthread_key_setname_np(
	  pthread_key_t *key,
	  const char *name,
	  void *mbz );


LIBRARY

  DECthreads POSIX 1003.1c Library (libpthread.so)


PARAMETERS

  key Address of the thread-specific data key object whose object name is to
      be changed.

  name
      Object name value to copy into the thread-specific data key object.

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


DESCRIPTION

  This routine changes the object name in the thread-specific data key object
  specified by key to the value specified by name.  To set a new thread-
  specific data key object's object name, call this routine immediately after
  initializing the key object.

  The object name is a C language string and provides an identifier that is
  meaningful to a person debugging a 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 key is not a valid key, or the length in
      characters of name exceeds 31.

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


ERRORS

  None
