Defined in locale.h, this function selects
the appropriate locale as specified by the category and locale arguments.
SyntaxThe setlocale() function is used to change
or query part or all of the current locale. The effect of the category
argument for each value is:
LC_COLLATEAffects the behavior of
strcoll().LC_CTYPEAffects the behavior of the character handling functions.
LC_MONETARYAffects the monetary formatting information returned by
localeconv().LC_NUMERICAffects the decimal-point character for the formatted input/output functions and the string conversion functions and the numeric formatting information returned by
localeconv().LC_TIMECan affect the behavior of
strftime(). For currently supported locales, the option has no effect.LC_ALLAffects all locale categories. This is the bitwise OR of all the locale categories.
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.
Valid locale __use_symbols
are imported (X_ctype __use_iso8859_ctype, __use_sjis_ctype, __use_utf8_ctypte),
and on user-defined locales.
If a pointer to a string is given for locale
A null pointer for locale
If categoryLC_ALL and
the most recent successful locale-setting call uses a category other
than LC_ALL, a composite string might be returned.
The string returned when used in a subsequent call with its associated
category restores that part of the program locale. The string returned
is not modified by the program, but might be overwritten by a subsequent
call to setlocale().
