|
|
|
#include <locale.h>
|
|
|
|
|
locale_t freelocale(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.
