11 | SYNOPSIS |
---|
12 | #include <locale.h> |
---|
13 | locale_t freelocale(locale_t <[locobj]>); |

17 | DESCRIPTION |
---|
18 | The <<freelocale>> function shall cause the resources allocated for a |
---|
19 | locale object returned by a call to the <<newlocale>> or <<duplocale>> |
---|
20 | functions to be released. |
---|
21 | |
---|
22 | The behavior is undefined if the <[locobj]> argument is the special locale |
---|
23 | object LC_GLOBAL_LOCALE or is not a valid locale object handle. |
---|
24 | |
---|
25 | Any use of a locale object that has been freed results in undefined |
---|
26 | behavior. |
---|
27 | |
---|
28 | RETURNS |
---|
29 | None. |
---|
30 | |
