uselocale(3)            Library Functions Manual            uselocale(3)

НАЗВАНИЕ

       uselocale - set/get the locale for the calling thread

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <locale.h>

       locale_t uselocale(locale_t newloc);

   Feature Test Macro Requirements for glibc (see
   feature_test_macros(7)):

       uselocale():
           Since glibc 2.10:
               _XOPEN_SOURCE >= 700
           Before glibc 2.10:
               _GNU_SOURCE

ОПИСАНИЕ

       The uselocale() function sets the current locale for the calling
       thread, and returns the thread's previously current locale.
       After a successful call to uselocale(), any calls by this thread
       to functions that depend on the locale will operate as though the
       locale has been set to newloc.

       The newloc argument can have one of the following values:

       A handle returned by a call to newlocale(3) or duplocale(3)
              The calling thread's current locale is set to the
              specified locale.

       The special locale object handle LC_GLOBAL_LOCALE
              The calling thread's current locale is set to the global
              locale determined by setlocale(3).

       (locale_t) 0
              The calling thread's current locale is left unchanged (and
              the current locale is returned as the function result).

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       On success, uselocale() returns the locale handle that was set by
       the previous call to uselocale() in this thread, or
       LC_GLOBAL_LOCALE if there was no such previous call.  On error,
       it returns (locale_t) 0, and sets errno to indicate the error.

ОШИБКИ

       EINVAL newloc does not refer to a valid locale object.

СТАНДАРТЫ

       POSIX.1-2008.

ИСТОРИЯ

       glibc 2.3.  POSIX.1-2008.

ПРИМЕЧАНИЯ

       Unlike setlocale(3), uselocale() does not allow selective
       replacement of individual locale categories.  To employ a locale
       that differs in only a few categories from the current locale,
       use calls to duplocale(3) and newlocale(3) to obtain a locale
       object equivalent to the current locale and modify the desired
       categories in that object.

ПРИМЕРЫ

       See newlocale(3) and duplocale(3).
