File Descriptions

Descriptions appearing in directory listings are produced by this module. This may be overridden by another module for those who which descriptions to come from somewhere else. 


#ifndef HTDESCRIPT_H
#define HTDESCRIPT_H

Description File

This module gets descriptions from the file defined by global variable HTHTDesctiptionFile in the same directory. The default value is .www_descript: 
extern char * HTDescriptionFile;
In the description file lines starting with a word starting with 'D' are taken to be descriptions (this looks funny now, but this is to make it easy to extend these description files to contain also other information. 
/*
 * Example:
 *	DESCRIBE  welcome.html	Our welcome page
 *	DESCRIBE  map*.gif	Map as a GIF image
 *	DESCRIBE  map*.ps	Map as a PostScript image
 */

HTML Titles

If description is not specified for a file that is of type text/html, this module uses the HTML TITLE as the description. This feature can be turned off by setting the HTPeekTitles variable to false. 
extern BOOL HTPeekTitles;

Read Description File

The description file for a directory is read in only once by HTReadDescriptions(), and the result returned by it is given as an argument when finding out a description for a single file. 
PUBLIC HTList * HTReadDescriptions PARAMS((char * dirname));

Get Description For a File

Once description file has been read and the list of descriptions is returned by HTReadDescriptions(), the function HTGetDescription() can be used to get a description for a given file: 
PUBLIC char * HTGetDescription PARAMS((HTList *	descriptions,
				       char *	dirname,
				       char *	filename,
				       HTFormat	format));
Directory name has to be present because this function may then take a peek at the file itself (to get the HTML TITLE, for example). If format is WWW_HTML and description is not found, this module may be configured to use the HTML TITLE as the description.

No string returned by this function should be freed!

Freeing Descriptions

Once descriptions have been gotten, the description list returned by HTReadDescriptions() must be freed by HTFreeDescriptions(): 
PUBLIC void HTFreeDescriptions PARAMS((HTList * descriptions));

#endif /* !HTDESCRIPT_H */
