Convert WCHAR string to lower case C

Question

I have a code:

WCHAR * cmp = L"TEST";

Need a function which would return this string in lower case!

Thanks!

Answer 1

Based on the WCHAR , you're presumably using (some version of) VC++. In this case, you want to use _wcslwr or _wcslwr_s . You normally do not want to use tolower or toupper on wide character strings.
