C++ , winapi Compare two WCHAR * strings

Question

I want to compare two WCHAR* strings.

How to do it?

P.S. I would like to ignore case while comparing.

I know you can use strcmpi but it id not working for WCHAR*.

Answer 1

For case sensitive comparison, look at wcscmp

For case insensitive comparison, look at _wcsicmp

@SoumyajitRoy I'm sure something exists, but this question was tagged winapi. – Skyjack

Answer 2

You have to use the WCHAR_t versions of strcmp. You can find the definitions here.

For case insensitive comparison use wcscasecmp.

Answer 3

Have you considered using StrCmpLogicalW()? Depending on your need that might be preferable to wcscmp.

Again, this is case sensitive. – Pteridophyte

No, it's not, take a look at the MSDN page. :-) – Gallantry

However, StrCmpLogicalW would care for prefix numbers in string. – Aspiration

Answer 4

There is lstrcmpi function in Win32 API which works with LPCTSTR instead of const char *. Don't know why it is not popular - I use it since 1994 (mostly lstrcmp without "i").
