Server: The server is the central component of the networking system, responsible for managing connections, handling incoming messages, and sending responses to clients. It initializes networking components, subscribes to relevant events, and enters a listening state to accept client connections. Upon receiving a message, the server processes it based on the message type and content, performs necessary actions, updates its internal state, and sends a response back to the client. The server gracefully handles errors and client disconnections, ensuring the smooth operation of the networking system.

Client: The client initiates a connection to the server using the server's IP address and port number. Once connected, the client can send messages to the server by populating a send buffer with the message data and its length. The client listens for incoming messages from the server and processes them based on the message type and content. It may update its internal state, display information to the user, or perform specific actions based on the received messages. The client handles errors and connection losses appropriately, ensuring reliable communication with the server.

The ProcessMessage() function handles sending and receiving messages between the client and server using send and receive buffers.

It checks if the send queue (m_sendQueue) has messages to send. If so, it populates the send buffer (m_sendBuffer) with the message data, considering the send buffer size (m_config.m_sendBufferSize). Large messages are split and sent in chunks.

The receive buffer size (m_config.m_recvBufferSize) determines the maximum data that can be received in a single read. The function reads incoming data into the receive buffer (m_recvBuffer).

If the entire message is sent successfully, the send buffer is cleared, and the send queue is updated. The send queue stores outgoing messages until they are sent.

If the send operation returns 0, it means the socket connection is closed, and the function returns false.
