HP C/iX Library Function Descriptions

setlocale

—Iflocale is not speciﬁed (an empty string is used), as in the following example,

setlocale (category,"")

the locale is set according to the following scheme:

1. If an equivalent 'LC_' environment variable is set, the language is set to the

language speciﬁed by the variable.

2. If the environment variable LANG is set, the language is set as speciﬁed by LANG.

3. If the JCW NLUSERLANG or NLDATALANG is set:

—ForLC_COLLATE and LC_TYPE, the language is set as speciﬁed by NLDATALANG.

—ForLC_TIME, LC_MONETARY and LC_NUMERIC, the language is set as speciﬁed by

NLUSERLANG.

— Otherwise, locale is set to be the C-locale.

• When Locale is Null

— If the locale is a null pointer, the setlocale function returns the current locale of

the named category to the program. For example,

setlocale (LC_MONETARY,NULL);

returns to the program the locale that is set for monetary processing. This is a query

operation that does not change the locale environment of the program.

NOTE

The default locale is always the C-locale.
