Thread: newbie question

Here my prob i try to start my code but i not sure it well connect.here it is.


#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <stdio.h>

int connect(int sockfd, const struct sockaddr serv addr, socklen_t addrlen);



That how i start it so far.did i make any mistakes?

Depends on whether you're using Windows or Unix. If Windows you'll need to use winsock. For Unix, you're looking good so far here is some more info.

yes i useing linux but i am takeing alot of notes when i doing this

Before you connect(), you must create the socket(), and fill out the sockaddr_in struct. I suggest checking out Beej's Network Programming Tutorial, read it carefully and run the example code, and then check out and search the Networking/Device Communication section of the boards for relevent threads, search the internet, whatever.

Also, just:

Code:

int connect(int sockfd, const struct sockaddr serv addr, socklen_t addrlen);

Won't do anything by itself. It is a function prototype specifying the parameters it takes. A call to the connect function in your code might look like: connect(Socket, (struct sockaddr*)&hostAddr, sizeof(struct sockaddr)), where Socket is the int returned from the socket() function, and hostAddr is the filled out sockaddr_in struct.
