Helo,

I'm trying to write a packet generator using wpcap.dll
but I have a problem with creating a packet.

Suppose I'm able to create a ethernet header and a
packet header. How can I make from these two structure
a pointer to u_char?
This is my problem:


const u_char *packet

struct ethernet_header{
        u_char ether_dhost[6];
        u_char ether_shost[6];
        u_short ether_type;
        };

struct ip_header{

        ...
        
        }; 


ethernet_header ethernet;
ip_header ip;

//?how do I push 'ethernet' and 'ip' into 'packet'?



Thanks,
Kenny Cauwerts
