What is the need of accept() function????

gouriproutray · 27-11-07, 10:52 PM

In socket programing(tcp/ip)..we use socket() function to get the socket file descriptor.
And using the accept() function again this function gives another socket file descriptor.
My question is ????????
What is the need of accept() function to get file descriptor when we have already one file descriptor by using socket() function.

Gouriproutray,

If you are talking about java network programming, as far as I remember there is not accept() method in Socket class. But it is the method of ServerSocket class.

Here, SeverSocket is server (running at a specified port) which listens to all requests and accepts new requests using accept() method which returns Socket class using which we can perform IO operations.

Simple here you can treat ServerSocket as Server and Socket as a request/client.

Thanks,
Krishna
