nl_langinfo -- Query language and locale information

Description

string nl_langinfo ( int item)

nl_langinfo() is used to access individual elements of the locale categories. Unlike localeconv(), which returns all of the elements, nl_langinfo() allows you to select any specific element.

If item is not valid, FALSE will be returned.

item may be an integer value of the element or the constant name of the element. The following is a list of constant names for item that may be used and their description. Some of these constants may not be defined or hold no value for certain locales.
