Question HELP broadcasting client IDs to network in C

I am trying to write a client server chat program in C and am unsure as to how I would broadcast all the users IDs over the network. At the moment I have the usernames stored in a array clientsock[sock].cl_id, I am able to output this information to the server but am unsure how to transmit this information to all the users.

If someone could help me to understand how to transmit string from an array element over a network I would be very grateful.

Thank you in advance.

I don't know which sockets you use ..

I think for a chat server it is datagram sockets that we generally use. If so you can transmit your array to the server by making use of a buffer variable on both the client and server.

you use the function htons(); as part of the POSIX standard..

which converts the array to the network byte order ..

In the server use ntohs(); to diassemble.

bye
