sockets - Assigning IP address in IP Header in C -

I am implementing a chat room application using raw sockets for my college project in C. I have problem in specifying IP address I

is received from the packet socket as I have shown I am parsing it now how to specify IP address.

I want to do it as shown (using RCVIP as a four), if possible. So before suggesting to use struct in_addr , help me with this because I have tried other methods which are causing me other illusions.

  main () {char * rcv_ip; Four * packet; Int len; Struct iphdr ip_header; Rcv_ip = ParseIPHeader (packet, lane); Printf ("\ n% s", rcv_ip); // Printing some junk printfrog ("\ n% s", inet_addr (rcv_ip)); // give mistake print ("\ n% s", inet_ntoa (* ((struct in_addr *) ip_header-> daddr)); // Printing ip ip_header CreateIPHeader (rcv_ip + 5, rcv_ip); }   
 Now the ParseIPHeader function.  
  char * parse header (packet, lane) {struct iphdr * ip_header; Struct ethhdr * eth_header; Char * ret_ip; Ip_header = (Straight IPHR *) (Packet + Size (Stret Etherthur)); Ret_ip = malloc (10); Memset (ret_ip, 0, 10); memcpy (ret_ip, & amp; ip_header-> daddr), sizeof (ip_header-> daddr)); Memcpy (ret_ip + 5, & amp; ip_header- & gt; saddr), 4); Return ret_ip; } Struct iphdr * CreateIPHeader (char * src_ip, char * dst_ip) {struct iphdr * ip_header; Ip_header = malloc (formation (structure IPHDR)); //main part. how to do this?? Ip_header-> Saddr = inet_addr (src_ip); //please correct it. Ip_header-> Daddr = inet_addr (dst_ip); Return (ip_header); }   
 thanks :)   
 
 
 Hope you IP addresses String because you try to print one with the  printf ()  and % s  format specifier. this is wrong; The IP addresses are binary in the header.  
 This means that an IPv4 address uses only 32 bits, while the text's representation can be greater than 3 + 1 + 3 + 1 + 3 + 1 + 3 = 15 characters (Plus terminator, therefore 16).
