4.6.11 setlocale()
Selects the appropriate locale as specified by the category and locale arguments.
Syntax
char* setlocale(int category, const char* locale)
Implementation
The
setlocale()
function is used to changeor query part or all of the current locale. The
effect of the category argument for each value is described below. A value of
"C"
for
locale specifies the minimal environment for C translation. An empty string,
""
, for
locale specifies the implementation-defined native environment. At program startup the
equivalent of
setlocale(LC_ALL, "C")
is executed.
The values of
category
are:
LC_COLLATE
Affects the behavior of
strcoll().
LC_CTYPE Affects the behavior of the character handling functions.
LC_MONETARY
Affects the monetary formatting information returned by
localeconv()
.
LC_NUMERIC
Affects the decimal-point character for the formatted input/output
functions and the string conversion functions and the numeric formatting
information returned by
localeconv()
.
LC_TIME Can affect the behavior of
strftime()
. For currently supported locales,
the option has no effect.
LC_ALL Affects all locale categories. This is the bitwise OR of the above
categories.
Returns
If a pointer to string is given for
locale
and the selection is valid, the string associated
with the specified category for the new locale is returned. If the selection cannot be
honored, a null pointer is returned and the locale is not changed.
A null pointer for
locale
causes the string associated with the category for the current
locale to be returned and the locale is not changed.
