newlocale – Creates a new locale



Standard C Library (libc, -lc)


#include <locale.h>

newlocale(int mask, const char * locale, locale_t base);


Creates a new locale, inheriting some properties from an existing locale. The mask defines the components that the new locale will have set to the locale with the name specified in the locale parameter. Any components not specified in mask will be inherited from the locale referenced by base, if base is not NULL. If the call is successful, the state of the locale referenced by base is unspecified, and it must not be accessed. The special locale LC_GLOBAL_LOCALE may not be specified for base. The mask is either LC_ALL_MASK, indicating all possible locale components, or the logical OR of some combination of the following:
LC_COLLATE_MASK The locale for string collation routines. This controls alphabetic ordering in strcoll(3) and strxfrm(3).
LC_CTYPE_MASK The locale for the ctype(3) and multibyte(3) functions. This controls recognition of upper and lower case, alphabetic or non-alphabetic characters, and so on.
  Set a locale for message catalogs, see catopen(3) function.
  Set a locale for formatting monetary values; this affects the localeconv(3) function.
LC_NUMERIC_MASK Set a locale for formatting numbers. This controls the formatting of decimal points in input and output of floating point numbers in functions such as printf(3) and scanf(3), as well as values returned by localeconv(3).
LC_TIME_MASK Set a locale for formatting dates and times using the strftime(3) function.
This function uses the same rules for loading locale components as


Returns a new, valid, locale_t or NULL if an error occurs. You must free the returned locale with freelocale(3).


duplocale(3), freelocale(3), localeconv(3), querylocale(3), uselocale(3), xlocale(3)


This function conforms to IEEE Std 1003.1-2008 ("POSIX.1").

If you have a problem and you think awk(1) is the solution, then you have two problems.
