os.setlocale (locale [, category])
Sets the current locale of the program. locale
is a system-dependent string specifying a locale; category
is an optional string describing which category to change: "all"
, "collate"
, "ctype"
, "monetary"
, "numeric"
, or "time"
; the default category is "all"
. The function returns the name of the new locale, or nil if the request cannot be honored.
If locale
is the empty string, the current locale is set to an implementation-defined native locale. If locale
is the string "C
", the current locale is set to the standard C locale.
When called with nil as the first argument, this function only returns the name of the current locale for the given category.
This function may be not thread safe because of its reliance on C function setlocale
.
