Smile FD_ISSET in Select function Socket Programming

Hello I'm a newbie for Socket Programming.

Can someone explain me what this FD_ISSET(FD , fd_set) does?..

I want to send data to some clients in a Socket program. Can I use the FD_ISSET function to check the availability of clients??..

Yes, you can use FD_ISSET to check whether the socket is ready. Normally, it bind with select() function to support concurrent server.
