How to create a new CGI and integrate it ?

[Bouffanet, Fabrice]

Hello,
 
I want to add a new CGI into Nagios CGI.
This CGI need to get CGI parameters (host for example)
 
In order to get these variables, i'm trying to use a function process_cgivars.
This function looks like process_cgivars like in extinfo.c script.
 
The new function looks like :
 
int process_cgivars(void){
        char **variables;
        int error=FALSE;
        int x;
        variables=getcgivars();
        for(x=0;variables[x]!=NULL;x++){
                if(strlen(variables[x])>=MAX_INPUT_BUFFER-1){
                        x++;
                        continue;
                        }
                else if(!strcmp(variables[x],"host")){
                        x++;
                        if(variables[x]==NULL){
                                error=TRUE;
                                break;
                                }
                        host_name=strdup(variables[x]);
                        if(host_name==NULL)
                                host_name="";
                        }
        }
        free_cgivars(variables);
        return error;
}

I'm compiling this program with :
dpkg-buildpackage
and install the new version with :
dpkg -i nagios-mysql.deb
 
When i'm trying to display the page, i get the following page :
