CFStrings on Win32

[Dave Addey <listmail1 at dsl dot pipex dot com>]

Hi all,

I¹ve got my Win32 QuickTime-using plugin compiling now, pretty much.  But,
one thing is causing me problems.  I need to convert a REALstring into a
CFString ­ on Windows.  And I can¹t find a way to do so.

³But surely there isn¹t such a thing as CFString on Windows?², you cry.
Well, if you have the QuickTime Windows SDK installed, it contains a whole
bunch of Win32 wrappers for common mac types such as all the CFObjects, and
also lots of CoreAudio types.  It uses these wrappers to provide a common
API on Mac and Windows.  So, it expects the (wrapper) CFStrings, CFURLs and
so on on Win32 too.

I tried this (where inParameters->Location is a REALstring):

        const char *LocationCString = REALCString(inParameters->Location);
        if (LocationCString == NULL)
        {
            return -1;
        }
 
        CFStringRef LocationCFString = CFStringCreateWithCString(NULL,
LocationCString, REALGetStringEncoding(inParameters->Location));
        if (LocationCFString == NULL)
        {
            return -1;
        }

This second call always returns NULL.

I tried passing the output from REALCString to the Windows debugging
function OutputDebugString:

        OutputDebugString(LocationCString);

....and I got a whole bunch of high-ASCII mixed characters, not what I was
expecting at all.  On a MachO compile, the string is returned as expected
and the CFString is created okay.

Any ideas?  Are CStrings different on Windows somehow?  Help much
appreciated, as I¹m at a loose end without a way to get a CFString.

Dave.
