Siege durak/Podkidnoy (Throw-in) durak

Description

Network game. Client and server are written in pure C.
For network communication the socket system with TCP/IP protocol is used. Due to this it is possible to use streaming through read and write system calls, and there is a guarantee that the data will arrive in strict order.
The client and server are written in an event-driven programming model. Events are selected using the select system call, thus multiplexing I/O.

GUI: console version.
Card suits are labeled as %, #, v, ^.
Card ranks: 2, 3, 4, 5, 6, 7, 8, 9, 9, 10, J, Q, K, A.
There are several stages: attacking, defending, and tossing cards. Unlike classic Fool's game, here you can toss cards depending on the reaction of the players --- whoever has time to toss a card, that card goes on the table.

There are hints to help players.

When attacking: those cards that have the same ranks (or all of them).
When defending: those cards that can be used to beat back the attacking card on the table (higher rank, or with a trump suit).
When tossing: those cards that have the same rank.

It is possible to give up defense and accept attacking cards -- then press enter. It is also possible to discard the toss -- also press enter.
The server analyzes whether the defender can fight back. If so, the server analyzes whether the defender can fight back.
The defender is shown one card at a time (the others see all cards), which he must defeat. If the server decides that the defender does not have any cards that can be used to fight off the attacking cards, then the tossing phase is analyzed.
If the other players (except the defender, of course) have cards with the same rank as on the table, then the player moves to the tossing phase, otherwise the player moves to a new attack phase.

Use for your server

Build the server executable file.
Run the file on the command line, specify a free port to be used by the server (from 1024 to 65535) as the second argument.
Example: ./server 1025
Open the linux_client/client.c (or windows_client/client.c) file with any text editor.
On line 14, change the ip from 109.107.161.30 to %server ip-address% (either 127.0.0.1 if you want to test on a local computer).
On line 15 in the same file, correct the port to the one specified above.
Build the client file and run it without arguments.
