C++ wchar_t * equals case-insensitive to other wchar_t *

Question

Im trying to check if a wchar_t * equals case-insensitive to another wchar_t *. Can someone put me in the right way?

There is what I tryed:

wchar_t *vectored[80] = { ... };
int i = 0;
int j = 1;
_Towlower(vectored[i], NULL) == _Towlower(vectored[j], NULL);

_Tolower() no overload for wchar_t pointer.

Thanks you.

Are you sure you're not using _towlower (lowercase t)? If so, _towlower converts a single character, not a complete string. To compare a complete string, use _wcsicmp.

You could use the wcscasecmp function if it's available in your implementation.

Or _wcsicmp if you use Windows. – user1952500 Jan 10 '13 at 23:34
wchar.h dosn't contains wcscasecmp in windows. – Marcos Eusebi Jan 10 '13 at 23:37
@Marcos Eusebi In Windows you can use _wcsicmp – Daniel Martín Jan 10 '13 at 23:41
