-FUNCTION
-<<__tz_lock>>, <<__tz_unlock>>---lock time zone global variables
-
-INDEX
-	__tz_lock
-INDEX
-	__tz_unlock
-
-ANSI_SYNOPSIS
-	#include "local.h"
-	void __tz_lock (void);
-	void __tz_unlock (void);
-
-TRAD_SYNOPSIS
-	void __tz_lock();
-	void __tz_unlock();

-DESCRIPTION
-The <<tzset>> facility functions call these functions when they need to
-ensure the values of global variables.  The version of these routines
-supplied in the library use the lock API defined in sys/lock.h.  If multiple
-threads of execution can call the time functions and give up scheduling in
-the middle, then you you need to define your own versions of these functions
-in order to safely lock the time zone variables during a call.  If you do
-not, the results of <<localtime>>, <<mktime>>, <<ctime>>, and <<strftime>>
-are undefined.
-
-The lock <<__tz_lock>> may not be called recursively; that is,
-a call <<__tz_lock>> will always lock all subsequent <<__tz_lock>> calls
-until the corresponding <<__tz_unlock>> call on the same thread is made.
