Hi,
Here is a segment of code...I did used tvb_get_ntohl();
=============================================
static int ac_user_ip = -1;
guint32 user_ip; //user ip defined
tvb_memcpy(tvb, (guint8 *)&iph, offset, sizeof(e_ip));
iph.ip_len = g_ntohs(iph.ip_len);
iph.ip_id = g_ntohs(iph.ip_id);
iph.ip_off = g_ntohs(iph.ip_off);
iph.ip_sum = g_ntohs(iph.ip_sum);
//retrieve the User IP Address from the packet
user_ip = tvb_get_ntohl(tvb, offset);
proto_tree_add_ipv4 (ac_tree, ac_user_ip, tvb, offset + 4, -4,
user_ip);
=================================================
