Here is the same thing (I think) that I use

short constructPath(cRecPtr,pathName,dirID)
CInfoPBRec	*cRecPtr;
char		*pathName;
long		dirID;

{
char		buffer[32];
short		error;

	if (dirID == 1)
		return(0);
		
	cRecPtr->dirInfo.ioDrDirID = dirID;
	cRecPtr->dirInfo.ioNamePtr = buffer;
	cRecPtr->dirInfo.ioFDirIndex = -1;
	if (error = PBGetCatInfo(cRecPtr,false))
		return(error);
	
	if (error = constructPath(cRecPtr,pathName,cRecPtr->dirInfo.ioDrParID))
		return(error);
	
	BlockMove(&(buffer[1]),&(pathName[pathName[0]+1]),buffer[0]);
	pathName[0] += buffer[0];
	pathName[++pathName[0]] = ':';

	return(0);
}

It basically stacks all the names as it follows up to the root, and copies
on the way back down.  Interesting, I thought (when I think).
