Typecast struct sockaddr in struct sockaddr_in
I have a very interesting problem while making a simple client server program in c. i am wokring on linux kernel-220.127.116.11 . While creating a socket for my server program i want to bind it with a port. for which i used following code
struct sockaddr_in sad;
memset((char *)&sad,0,sizeof(sad)); /* clear sockaddr structure */
sad.sin_family = AF_INET; /* set family to Internet */
sad.sin_addr.s_addr = INADDR_ANY; /* set the local IP address */
sad.sin_port = htons((u_short)port);/* set the port number */
if (bind(welcomeSocket, (struct sockaddr *)&sad, sizeof(sad)) < 0)
Now in this bind call sad is converted in struct sockaddr *. Now after this code what i want to do for some experiment
struct sockaddr *a;
struct sockaddr_in *b;
a=(struct sockaddr *)&sad;
b=(struct sockaddr_in *)a;
now i want to extract all the members of structure b .. but i am getting incompatible reference pointer error. I just want to typecats a struct sockaddr into sockaddr_in and extract all of its data members. Please help me.
Thank you in advance...
