google search client api for c/c++
By littlestar,2003,TRS Open Lab

Google 网站上提供了goole search client api for Java和for dot.net的版本,大家可以参考.

For C/C++的版本特点如下
内置XML解析器.
内置gbk/utf-8编码/解码器(包含GBK编码表)
采用Pure C编写,采用标准C接口.
支持http代理.

用户需要在http://api.google.com/createkey申请key
演示程序中的key是一个网友给我的,仅供测试用，演示程序中的代理可能连接不上,由于没有设置超时,可能处于等待状态(sorry.....)
函数中各个参数的意义和http://www.google.com/apis/reference.html的说明一样,对此不作过多的介绍.

建议在此基础上开发二次应用,如封装成COM,但不得对作者提供的api进行反编译.
如需转载,请注明原作者,谢谢合作.
欢迎交流.
