40 SYNOPSIS
41 #include <locale.h>
42 locale_t freelocale(locale_t <[locobj]>);
43
44 locale_t _freelocale_r(void *<[reent]>, locale_t <[locobj]>);
45
46 DESCRIPTION
47 The <<freelocale>> function shall cause the resources allocated for a
48 locale object returned by a call to the <<newlocale>> or <<duplocale>>
49 functions to be released.
50
51 The behavior is undefined if the <[locobj]> argument is the special locale
52 object LC_GLOBAL_LOCALE or is not a valid locale object handle.
53
54 Any use of a locale object that has been freed results in undefined
55 behavior.
56
57 RETURNS
58 None.
59
60 PORTABILITY
61 <<freelocale>> is POSIX-1.2008.
