locale.h — category macros
SYNOPSIS
#include
DESCRIPTION
Some of the functionality described on this reference page extends the ISO C standard. Applications shall define the appropriate feature test macro (see the System Interfaces volume of POSIX.1-2017, Section 2.2, The Compilation Environment) to enable the visibility of these symbols in this header.

which shall expand to integer constant expressions with distinct values for use as the first argument to the setlocale() function.
Additional macro definitions, beginning with the characters LC_ and an uppercase letter, may also be specified by the implementation.
The
In addition, a macro to set the bits for all categories set shall be defined: LC_ALL_MASK
The
The
The following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided for use with ISO C standard compilers.
locale_t duplocale(locale_t);
void freelocale(locale_t);
struct lconv *localeconv(void);
locale_t newlocale(int, const char *, locale_t);
char *setlocale(int, const char *);
locale_t uselocale (locale_t);
The following sections are informative.
APPLICATION USAGE
None.
RATIONALE
It is suggested that each category macro name for use in setlocale() have a corresponding macro name ending in _MASK for use in newlocale().
FUTURE DIRECTIONS
None.
