wctolower()

Return the lowercase equivalent of a wide character

Synopsis:

wchar_t wctolower( wchar_t wc );

Description:

The wctolower() function returns the lowercase equivalent of wc, or wc itself if there's no lowercase equivalent. It's similar to tolower(), except that it knows about Unicode characters.

This function is optimized for size rather than speed. If speed is important, use wctolower() to create a full Unicode conversion table and then index into it directly.

Returns:

The equivalent lowercase character, or the given character itself if there's no lowercase equivalent.
