NAME

nl_langinfo – language information

CONTENTS

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <langinfo.h>

char *
nl_langinfo(nl_item item);

char *
nl_langinfo_l(nl_item item, locale_t loc);

DESCRIPTION

The nl_langinfo() function returns a pointer to a string containing information relevant to the particular language or cultural area defined in the program or thread's locale, or in the case of nl_langinfo_l(), the locale passed as the second argument. The manifest constant names and values of item are defined in <langinfo.h>.

Calls to setlocale() with a category corresponding to the category of item, or to the category LC_ALL, may overwrite the buffer pointed to by the return value.

RETURN VALUES

In a locale where langinfo data is not defined, nl_langinfo() returns a pointer to the corresponding string in the POSIX locale. nl_langinfo_l() returns the same values as nl_langinfo(). In all locales, nl_langinfo() returns a pointer to an empty string if item contains an invalid setting.

EXAMPLES

For example:

    nl_langinfo(ABDAY_1)

would return a pointer to the string "Dom" if the identified language was Portuguese, and "Sun" if the identified language was English.

SEE ALSO

setlocale(3)
