SmartCard学习之libpcsclite

---

下面这一段代码，不是在所有卡片上都能成功运行。
写出来的意义是，让大家对于智能卡操作的流程有个大致了解，大致熟悉一下相关函数怎么用。
具体API文档，微软介绍的很清楚，网上也很多，不赘述。

基本上流程就是：

安装的库基本上就那么几样东西：

libccid pcscd libdbus-1-dev libpcsclite-dev
差不多就这几个吧，不够的就再查查，哈哈哈哈

make命令大致如下：

gcc -g -o smartcard smartcard.cpp -lpcsclite -I /usr/include/PCSC/
