Code required for socket emulator free?

Hello,

I have attached a server-side code that establishes connections with, and accepts messages from, clients with select().  I have used port 9999 for listening. You can use any free port. I have not defined functions and have let the main function do all things. Toward the bottom please  have a look at the "for" loop which is a bit large.

 

The code is not for sending data to individual clients from the server. But it is doable if coded. As you can't send data to a client using "select()", you need to do something different. You can send data with a socket "send()", just as the code reads data with "recv()". For example:

 

char *msg = "This is a piece of message.";

int len, bytes_sent;

/*   

Some lines of code to do something

*/

len = strlen(msg);

bytes_sent = send(sockfd, msg, len, 0);

 

To learn more about socket programming here is an excellent website. http://www.beej.us/guide/bgnet/output/html/multipage/index.html

 

Hope it helps.

 

Best Regards,

Parisi
