NAME

nl_langinfo - language information

 SYNOPSIS

#include <langinfo.h>

char *nl_langinfo(nl_item item);

 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's locale (see <langinfo.h>). The manifest constant names and values of item are defined in <langinfo.h>. 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.

Calls to setlocale() with a category corresponding to the category of item (see <langinfo.h>), or to the category LC_ALL, may overwrite the array pointed to by the return value.

This interface need not be reentrant.

 RETURN VALUE

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

This pointer may point to static data that may be overwritten on the next call.

 ERRORS

No errors are defined.

 EXAMPLES

None.

 APPLICATION USAGE

The array pointed to by the return value should not be modified by the program, but may be modified by further calls to nl_langinfo().

 FUTURE DIRECTIONS

None.
