8.3 Example CGI Code
Eddy-Serial DK has two CGI programs: getagent.cgi and setagent.cgi.
“getagent.c” reads an environment configuration file on /etc/ folder to HTML document , and “setagent.c”
saves user-modified information on the HTML document back the environment file on /etc/folder and saves it to
flash/, so the user-modified environment configuration is stored.
The following example shows processing part of getagent.c to display configuration value to HTML page as the
example above.
