Detailed Description
Socket general functions
- Date
- 2003-12-02
Mainly deals with initialization and higher level socket maintenance (checking for lost connections and if data has arrived.) The reading of data is handled in loop.c

◆ final_free_player()
| void final_free_player | ( | player * | pl | ) |
Sends the 'goodbye' command to the player, and closes connection.

◆ free_newsocket()
| void free_newsocket | ( | socket_struct * | ns | ) |
Frees a socket. Basically, all we need to do here is free all data structures that might be associated with the socket. It is up to the caller to update the list

| void init_connection | ( | socket_struct * | ns, |

Initializes a connection. Really, it just sets up the data structure, socket setup is handled elsewhere. We do send a version to the client.

Variable Documentation
◆ init_sockets
| socket_struct* init_sockets |
Established connections for clients not yet playing. See the page on the login process for a description of its use. Socket at index 0 is the socket listening for connections, and must not be freed. If this socket becomes invalid, then the server will try to reopen it. We also take the opportunity to set TCP_NODELAY - this forces the data in the socket to be flushed sooner to the client - otherwise, the OS tries to wait for full packets and will this hold sending the data for some amount of time, which thus adds some additional latency.
