i guess its the fromer one.
Code:
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>
#include <netinet/in.h>
int main ()
{
struct iphdr *ip;
ip = (struct iphdr *) malloc(sizeof(struct iphdr));
ip->ihl = 5;
ip->version = 4;
ip->tos = 0;
ip->tot_len = sizeof(struct iphdr) + 452;
ip->id = htons(getuid());
ip->ttl = 255;
ip->protocol = IPPROTO_TCP;
ip->saddr = inet_addr("127.0.0.1");
ip->daddr = inet_addr("127.0.0.1");
ip->check = in_cksum((unsigned short *)ip; sizeof(struct iphdr));
return 0;
}
i am getting a strange error:
"dereferencing pointer to an incomplete type."
is there something wrong with my pointer?
or what else?
thank you
cya
