c++ 使用zlib压缩文本

#include<iostream>
#include <stdlib.h>
#include "zlib.h"

#define MaxBufferSize 1024 * 100

#pragma comment (lib,"zlibstat.lib")

//http://www.winimage.com/zLibDll/
//需要下载 zlib123dllx64 和zlib-1.2.3.tar.gz ，
// 把zlib-1.2.3.tar.gz里面的zlib.h 和zconf.h 包含进来
// 把zlib123dllx64里面的库   zlibstat.lib包含进来

//Linux 安装
//1.将zlib-1.2.3.tar.gz解压并到zlib-1.2.3目录下
//2.配置安装目录
//./configure   --prefix=/usr/local/zlib
//3.编译
//make
//4.安装
//make install
//完成后在 / usr / local / zlib / 目录下会多出 include / , lib / 目录。
//可以将这两个目录加到自己的项目工程中去，使用zlib压缩，解压。
