#include <ace/Get_Opt.h>
#include <string>
#include <iostream>
using namespace std;

void usage()
{    
	cout << " 参数错误 " << endl;
	cout << " -h : 服务器IP" << endl;
	cout << " -p : 服务器端口" << endl;
	cout << " -d : 以调试模式运行" << endl;    
}

int main(int argc, char *argv[])
{
	if (argc < 2)
	{
		usage();
		return 1;
	}
	ACE_Get_Opt cmdline (argc, argv, "h:p:d");

	int cnt = 0;//必备参数计数器
	string host = "";
	int port = 0;
	bool debug = false;
	int cmd = 0;
	while ((cmd = cmdline()) != -1)
	{
		switch (cmd)
		{
		case 'h':
			{
				host = cmdline.opt_arg();
				cout << "host : " << host << endl;
				++cnt;
				break;
			}
		case 'p':
			{
				port = ACE_OS::atoi(cmdline.opt_arg());
				cout << "port : " << port << endl;
				++cnt;
				break;
			}
		case 'd':
			{
				debug = true;
				cout << "debug mode" << endl;
				break;
			}
		default :
			{
				usage();
				return 1;
			}

		}
	}

	if (cnt < 2)
	{
		usage();
		return 1;
	}

	return 0;//a.exec();
};
