towlower

Defined in header <wctype.h> 
wint_t towlower( wint_t wc );
-		 (since C95)

Converts the given wide character to lowercase, if possible.

-

Parameters

- -
wc - wide character to be converted

Return value

Lowercase version of wc or unmodified wc if no lowercase version is listed in the current C locale.

-

Notes

Only 1:1 character mapping can be performed by this function, e.g. the Greek uppercase letter 'Σ' has two lowercase forms, depending on the position in a word: 'σ' and 'ς'. A call to towlower cannot be used to obtain the correct lowercase form in this case.

-

ISO 30112 specifies which pairs of Unicode characters are included in this mapping.

-

Example

#include <locale.h>
-#include <stdio.h>
-#include <wchar.h>
-#include <wctype.h>
- 
-int main(void)
-{
-    wchar_t wc = L'\u0190'; // Latin capital open E ('Ɛ')
-    printf("in the default locale, towlower(%#x) = %#x\n", wc, towlower(wc));
-    setlocale(LC_ALL, "en_US.utf8");
-    printf("in Unicode locale, towlower(%#x) = %#x\n", wc, towlower(wc));
-}

Output:

-
in the default locale, towlower(0x190) = 0x190
-in Unicode locale, towlower(0x190) = 0x25b
