/******************************************************************************
Module:  HPSocket

Usage:
		方法一：
		--------------------------------------------------------------------------------------
		0. 应用程序包含 HPTypeDef.h / SocketInterface.h / HPSocket.h 头文件
		1. 调用 HP_Create_Xxx() 函数创建 HPSocket 对象
		2. 使用完毕后调用 HP_Destroy_Xxx() 函数销毁 HPSocket 对象

		方法二：
		--------------------------------------------------------------------------------------
		0. 应用程序包含 SocketInterface.h 和 HPSocket.h 头文件
		1. 创建 CXxxPtr 智能指针，通过智能指针使用 HPSocket 对象

*							TBT_ATTACH	：（附属）执行浅拷贝，但 TSocketTask 对象会获得 pBuffer 的所有权，并负责释放 pBuffer，避免多次缓冲区拷贝
