Question

I’m in the process of porting a C++ library from Linux to Windows, and am having problems with getuid(), which is not supported in Windows.

Any ideas what I can use in its place?

You can retrieves the name of the user associated with the current thread with GetUserName :

// ANSI version    
string GetWindowsUserNameA()
    {
        char buffer[UNLEN + 1] = {0};
        DWORD buffer_len = UNLEN + 1;
        if (!::GetUserNameA(buffer, & buffer_len))
        {
            // error handling
        }

        return string(buffer);
    }
