What Should the Listings Look Like?

You can set how the listings are to be sorted using the following flags.
typedef enum _HTNewsDirKey {
    HT_NDK_NONE		= 0,			/* Unsorted */
    HT_NDK_INDEX  	= 1,			/* Sort by Message Number */
    HT_NDK_DATE   	= 2,			/* Sort by date */
    HT_NDK_SUBJECT	= 3,			/* Sort by Subject */
    HT_NDK_FROM		= 4,			/* Sort by Sender */
    HT_NDK_GROUP	= 5			/* Sort group listing */
} HTNewsDirKey;

The News Listing Object

The news listing object handles the generation of a news listing. It is a bit like a stream in that it accept data, but it must be formatted in a special way which makes the normal stream architecture inadequate.

Create a News Listing Object

Creates a structured stream object and sets up the initial HTML stuff Returns the dir object if OK, else NULL
typedef struct _HTNewsDir HTNewsDir;
extern HTNewsDir * HTNewsDir_new (HTRequest * request, const char * title,
				  HTNewsDirKey key);

Add a Line to the List

This function accepts a news line. Everything except dir and nama can can be 0 or NULL. Returns YES if OK, else NO
extern BOOL HTNewsDir_addElement (HTNewsDir * dir, int index, char * subject,
				  char * from, time_t date, char * name,
				  int refs);

Free a News Listing Object

If we are sorting then do the sorting and put out the list, else just append the end of the list.
extern BOOL HTNewsDir_free (HTNewsDir * dir);
#endif /* HTNDIR */
