Export Coraza to C

[jptosso]

We need C wrappers in order to connect with other programs like Nginx and Apache.

We are going to copy the functions used by modsecurity but replacing msc_ with coraza_.

A sample would be:

#include "coraza/coraza.h"


char main_rule_uri[] = "basic_rules.conf";

int main (int argc, char **argv)
{
    Coraza *waf = NULL;
    Parser *parser = NULL
    Transaction *transaction = NULL;
    waf = coraza_init();

    parser = coraza_parser(waf);
    coraza_parser_read_file(main_rule_uri);

    transaction = coraza_new_transaction(waf);

    coraza_process_connection(transaction, "127.0.0.1");
    coraza_process_uri(transaction, "http://www.modsecurity.org/test?key1=value1&key2=value2&key3=value3&test=args&test=test");
    coraza_process_request_headers(transaction);
    coraza_process_request_body(transaction);
    coraza_process_response_headers(transaction);
    coraza_process_response_body(transaction);

    return 0;
}
