uselocale - set/get the locale for the calling thread
#include <locale.h>
locale_t uselocale(locale_t newloc);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
uselocale():
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:
On success, uselocale() returns the locale handle that was set by the previous call to uselocale() in this thread, or LC_GLOBAL_HANDLE if there was no such previous call. On error, it returns (locale_t) 0, and sets errno to indicate the cause of the error.
The uselocale() function first appeared in version 2.3 of the GNU C library.
POSIX.1-2008.
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.
See newlocale(3) and duplocale(3).
