VPN服务器已经存在，每个客户端去配置VPN太烦。能不能用PB调用API函数创建VPN连接？？
VPN服务器是固定公网IP，用户名密码都已知
------解决方案--------------------
做一个安装包，直接去安装
或者用pb做个模拟器，模拟一下安装VPN的过程
直接用api调用，应该不可行。

Routine Description:
Copies bytes from a packet into a buffer. Used to copy data
out of a packet during loopback indications.
Arguments:
Buf - the destination buffer
Packet - the source packet
Offset - the offset in the packet to start copying at
