Overview
This document provides a comprehensive guide to the Windows Winsock Connect API. It’s designed for developers building applications that interact with the Windows network stack.
This API provides fundamental functionality for establishing and managing connections to Windows network services, enabling client-server communication.
Win32 Connectivity
The core of the API revolves around handling Win32 connectivity events. These events signal the establishment or destruction of network connections.
Understand the different Win32 events – 'New Connection', 'Connection Destroyed', 'Connection Lost' are key.
Key Concepts
- 'Connection State': Indicates the current state of a connection (e.g., established, disconnected, failed).
- 'Connection ID': Unique identifier for a connection.
- 'Protocol': The protocol being used (e.g., TCP, UDP).
API Methods - Example
Here are some illustrative examples:
- Connect(const Connection*conn): Establishes a new connection.
- Connect(const Connection*conn, const string args): Establishes a connection and passes arguments.
- Disconnect(): Disconnects the connection.
- GetConnection(): Returns the current connection.
- Close(): Closes the connection.
Error Handling
The API includes error handling mechanisms. Common errors include: 'TimeoutError' when a connection is lost or there's a network problem.
