How about...
 int scavengeDirectory(dirName,vRefNum,wPtr)
...
 {
	Boolean	DeleteWD = true;
...
 	result	=	0;
...
 	do {
...
 		} else {
 			if (dirRec.ioFlFndrInfo.fdType == XPRCSignature) {
 				/*	Save vRefNum	*/
/* return the vRefNum if it was found, else return 0 */
 				result	=	dirWDRec.vRefNum;
				DeleteWD = false;
 			};
...
 		} while (err != fnfErr && !result);

/* don't delete the WD if it contains our file */
 		if (DeleteWD)
			PBCloseWD(&dirWDRec,false);
 	};
 
 	return(result);
 };

Of course, you could go one step further...
		if (!result) PBCloseWD(...)
and do away with DeleteWD.
