Re: coremidi & codewarrior

Thank you Laurent. Here is a solution for anyone else who runs into this
conversion problem. Note the solution below limits path names to 255
characters so it is NOT a complete solution. Also it uses c2Pstr which it
seems Apple is not encouraging.

void ConvertPathToUnixStyleMachOPath(StringPtr s)
{
CFStringRef path =
CFStringCreateWithPascalString(kCFAllocatorDefault, s,
CFStringGetSystemEncoding());
CFURLRef theURL =
CFURLCreateWithFileSystemPath(kCFAllocatorDefault,path,
kCFURLHFSPathStyle, false);
CFIndex bufLen = sizeof(Str255) - 1;
if (CFURLGetFileSystemRepresentation(theURL, true, s, bufLen))
c2pstr((char *)s);
CFAllocatorDeallocate(kCFAllocatorDefault, (void *)theURL);
CFAllocatorDeallocate(kCFAllocatorDefault, (void *)path);
}

Jeremy
