This header was originally in the C standard library as <locale.h>.

This header is part of the localization library

Types
lconv	formatting details, returned by std::localeconv (class)
Constants
NULL	implementation-defined null pointer constant (macro constant)
LC_ALLLC_COLLATELC_CTYPELC_MONETARYLC_NUMERICLC_TIME	locale categories for std::setlocale (macro constant)
Functions
setlocale	gets and sets the current C locale (function)
localeconv	queries numeric and monetary formatting details of the current locale (function)

Notes

• NULL is also defined in the following headers:
  • <cstring>
  • <ctime>
  • <cstddef>
  • <cstdio>
  • <cwchar>
