SYNOPSIS
#include <netinet/in.h>

const struct in6_addr in6addr_any;
const struct in6_addr in6addr_loopback;

DESCRIPTION
The in6addr_any variable is initialized by the system to contain the
wildcard IPv6 address (::).

The in6addr_loopback variable is initialized by the system to contain
the loopback IPv6 address (::1).

RETURN VALUE
None.

ERRORS
No errors are defined.

EXAMPLES
None.

APPLICATION USAGE
None.

RATIONALE
These variables were only described on the XBD <netinet/in.h>

CHANGE HISTORY
First released in Issue 8. Derived from Issue 7 XBD <netinet/in.h>.

Bug #811: precondition for mutex destruction unclear; example contradicts normative text Accepted as Marked
http://www.austingroupbugs.net/view.php?id=811

This item is tagged for TC2-2008.

On page 1643 line 53249 section pthread_mutex_destroy() change from:
Attempting to destroy a locked mutex or a mutex that is referenced
(for example, while being used in a pthread_cond_timedwait()
or pthread_cond_wait()) by another thread results in undefined
behavior.
to:
Attempting to destroy a locked mutex, or a mutex that another
thread is attempting to lock, or a mutex that is being used in
a pthread_cond_timedwait() or pthread_cond_wait() call by another
thread, results in undefined behavior.


On page 1647 lines 53424-53425 change:
A mutex can be destroyed immediately after it is unlocked. For
example, consider the following code:
to:
A mutex can be destroyed immediately after it is unlocked.
However, since attempting to destroy a locked mutex, or a mutex
that another thread is attempting to lock, or a mutex that is
being used in a pthread_cond_timedwait() or pthread_cond_wait()
call by another thread, results in undefined behavior, care
must be taken to ensure that no other thread may be referencing
the mutex.

On page 1647 delete lines 53426-53444.
