There are standard initialization things that you will want to do when using this library. The following template should give you some idea of how to properly use this library.
/* template using cgihtml.a library */
#include <stdio.h> /* standard io functions */
#include "cgi-lib.h" /* CGI-related routines */
#include "html-lib.h" /* HTML-related routines */
int main()
{
llist entries; /* define a linked list; this is where the entries */
/* are stored. */
/* parse the form data and add it to the list */
read_cgi_input(&entries);
/* The data is now in a very usable form. To search the list entries */
/* by name, call the function: */
/* cgi_val(entries, "nameofentry") */
/* which returns a pointer to the value associated with "nameofentry". */
html_header(); /* print HTML MIME header */
html_begin("Output"); /* send appropriate HTML headers with title */
/* <title>Output</title> */
/* display whatever data you wish here, probably with printf() */
html_end(); /* send appropriate HTML end footers (</body> </html>) */
list_clear(&entries); /* free up the pointers in the linked list */
return 0;
}
To compile your program with the library, include the file cgihtml.a when linking your object files. For example, if your main object file is program.cgi.o, the following should work successfully:
cc -o program.cgi program.cgi.o cgihtml.a
