/* PROGRAM: eggsh
* FILE: $Header: /home/egg/src/RCS/genlib.h,v 1.3 1999/02/28 20:05:35 ghn Exp $
* PURPOSE: Define general library interface
* AUTHOR: Greg Nelson
* DATE: 98-05-09
*
* REVISED:
* $Log: genlib.h,v $
* Revision 1.3 1999/02/28 20:05:35 ghn
* Version 5.1: Changed dquad2sockaddr interface to support ip/mm mask,
* created hl2dquad to translate host-long to dotted quad, and modified
* sockaddr2dquad to use this.
*
* Revision 1.2 1998/12/31 22:11:05 ghn
* Rev 5 code: includes multi-reg support, HTML, etc.
*
* Revision 1.1 1998/07/21 11:38:04 ghn
* Initial revision
