nl_init(S)

nl_init -- initializes native language support operation

Syntax

cc -a ods30 . . . -lc

int nl_init (lang)
char * lang;

Description

The nl_init routine is provided as an alternative interface to the setlocale(S) routine, for programs written to the X/OPEN Portability Guide, Issue 2, standard. However, nl_init has been withdrawn from XPG3.

The nl_init routine initializes native language support operation for the language identified by lang, which is a pointer to a string containing settings of language, territory and codeset as defined for the LANG environment variable (see environ(M)).

Typically, nl_init is used to bind program operation to the user's specified language requirements, for example:

   nl_init(getenv("LANG"));

A call to nl_init fails if the string pointed to by lang does not identify a valid language/territory/codeset combination. In this case, operation continues for the language identified on the last successful call.

Return value

If successful, nl_init returns 0 (zero). Otherwise,

1 is returned.

Notes

Calls to nl_init can be used to switch operation from one supported language to another. It is not necessary to call nl_init to set the initial language for an application; this is done by the automatic setlocale call at program startup.

The nl_init routine is not as flexible an interface as that provided by setlocale.
