| 9 | 16.9.7 Byte Stream Connection Server Example |
|---|
| 10 | The server end is much more complicated. Since we want to allow multiple clients |
|---|
| 11 | to be connected to the server at the same time, it would be incorrect to wait |
|---|
| 12 | for input from a single client by simply calling read or recv. Instead, the |
|---|
| 13 | right thing to do is to use select (see Waiting for I/O) to wait for input on |
|---|
| 14 | all of the open sockets. This also allows the server to deal with additional |
|---|
| 15 | connection requests. |
|---|
| 16 | |
|---|
| 17 | This particular server doesn't do anything interesting once it has gotten a |
|---|
| 18 | message from a client. It does close the socket for that client when it detects |
|---|
| 19 | an end-of-file condition (resulting from the client shutting down its end of the |
|---|
| 20 | connection). |
|---|
| 21 | This program uses make_socket to set up the socket address; see Inet Example. |
