htvms_waisprot.h

elinks下lynx是最重要的二个文本浏览器, 在linux下非常实用, lynx比elinks早的多, 目前好像停止开发, 这是lynx源代码

/*							HTVMS_WAISProt.h
**
**	Adaptation for Lynx by F.Macrides ([e-mail])
**
**	31-May-1994 FM	Initial version.

   3.26.90	Harry Morris, [e-mail]
   3.30.90  Harry Morris
			-	removed chunk code from WAISSearchAPDU,
			-	added makeWAISQueryType1Query() and readWAISType1Query() which
				replace makeWAISQueryTerms() and makeWAISQueryDocs().
   4.11.90  HWM - added definitions of wais element set names
   4.14.90  HWM - changed symbol for relevance feedback query from QT_3 to
				  QT_RelevanceFeedbackQuery added QT_TextRetrievalQuery as a
				  synonym for QT_BooleanQuery
				- renamed makeWAISType1Query() to makeWAISTextQuery()
				  renamed readWAISType1Query() to readWAISTextQuery()
   5.29.90  TS - added CSTFreeWAISFoo functions

/* wais-message.h
 *
 * This is the header outside of WAIS Z39.50 messages.  The header will be
 * printable ascii, so as to be transportable.  This header will precede each
 * Z39.50 APDU, or zero-length message if it is an ACK or NACK.  Be sure to
 * change hdr_vers current value if you change the structure of the header.
 *
 * The characters in the header are case insensitive so that the systems from
 * the past that only handle one case can at least read the header.
 *
 * 7.5.90 HWM - added constants
 * 7/5/90 brewster added funtion prototypes and comments
 * 11/30/90 HWM - went to version 2 (inits and typed retrieval)
