GetIndex

GetIndex is a C program that uses the W3C Reference Library version 2.7 (wwwlib2.7) [10] to get documents from WWW given the URL. The reason for using wwwlib2.7 is because it provides a good way of handling the WWW communication structure known as hypertext transfer protocol (HTTP) [4]. When the HTTP format changes, the wwwlib will try to accommodate these changes, keeping the interface standard between the library and the application. The wwwlib also allows the application to handle error messages according to its needs, thus GetIndex is capable of suppressing errors during loading.

The following file should be included in the Rumour package :

• getindex/src/get_index.c - This file is the source code for GetIndex.

• getindex/src/HTDummy.h - Provides a set of dummy function needed to use wwwlib.

• getindex/src/server.h - Header file for get_index.c

• getindex/Makefile - Makefile for GetIndex

• getindex/contrib - This directory contains the wwwlib2.7 that was used during the development.

Some of the function used in get_index.c include:

• Name : void HTErrorMsg (HTRequest * req) Function : Error handler for wwwlib.

• Name : int LoadIndex(char *f) Function : Loading Process.

• Name : void main (int argc, char *argv[]) Function : Main function.

Although GetIndex could be installed at different directories from the Rumour directory, a link is needed from the GetIndex that is executable to the same directory as the Collector.
