'opened by' is hard; go take a look at the fopen.c and iomisc.c to try
to figure out how to hand off a Mac file refNum to stdio FILE.

If you want to somehow do an fopen given an SFReply, that's fairly easy:
	short currVRefNum;	/* for saving current directory */
	SFReply sfr;
	FILE * fp;

	SFGetFile (...&sfr...);	/* or SFPutFile; be sure to use O_CREAT */
	if (sfr.good) {
		GetVol (NULL, &currVRefNum);
		SetVol (NULL, sfr.vRefNum);
		PtoCstr (sfr.fName);
		fp = fopen (sfr.fName, mode);
		SetVol (NULL, currVRefNum);
	} else
		fp = NULL;

This ought to be on the C.S.M.P FAQ list...
