## Overview

A simple network client-and-server demo written in C for UNIX-compliant systems, allowing simple chatting between a server and its clients. Features a command system, connection checking and dynamic allocation for the server.

## Usage

### Client

Run the client executable with the following arguments:

- address: The server's address or name. An example could be `localhost` or your device's name to connect to a server running on the same device, or an IP address.

- port: The port of the server. This can be a number between 1024 and 65535.

After connecting, you can type in a message to be sent to the server. Any incoming messages from the server will be shown as well.

### Server

Run the server executable with the following arguments:

- port: The port to start the server on. Follows the same rules as that of the client above.

- max-clients: The maximum number of clients allowed to be connected. A negative value will remove this limit.

- interactive-mode: A non-zero value will enable interactive mode, where you can type in commands as input, as specified below.

### Commands (server)

Commands written in the 'interactive' mode of the server are as follows (keywords are case-sensitive):

- exit: Initiates a clean shutdown of the server.

- stopint: Exits interactive mode. The server will continue running but no more commands can be issued.

- "\ \": Sends the given client ID the following message.

- "\ kick": Kicks the given client ID.

The 'ID' can instead be 'all' to operate on all connected clients.

## Build

To compile the client and server source files, you can run `make` with the provided [Makefile](Makefile).
