The following example program uses the following sequence of API calls:

Socket programming 113

1. The socket() API returns a socket descr iptor, which represents an endpoint. The statement also

identifies that the INET (Internet Protocol) address family with the TCP transport (SOCK_STREAM) is

used for this socket.

2. After the socket descr iptor is received, the connect() API is used to establish a connection to the

server.

3. The send() API sends the data buffer to the worker jobs.

4. The recv() API receives the data buffer from the worker jobs.

5. The close() API closes any open socket descr iptors.
