FUNCTION
<<freelocale>>---free resources allocated for a locale object
INDEX
freelocale
INDEX
_freelocale_r
ANSI_SYNOPSIS
#include <locale.h>
locale_t freelocale(locale_t <[locobj]>);
locale_t _freelocale_r(void *<[reent]>, locale_t <[locobj]>);
DESCRIPTION
The <<freelocale>> function shall cause the resources allocated for a
locale object returned by a call to the <<newlocale>> or <<duplocale>>
functions to be released.
The behavior is undefined if the <[locobj]> argument is the special locale
object LC_GLOBAL_LOCALE or is not a valid locale object handle.
Any use of a locale object that has been freed results in undefined
behavior.
RETURNS
None.
PORTABILITY
<<freelocale>> is POSIX-1.2008.
