求与SYSTEM命令类似，但不作为子进程执行的命令

[netreptile]

如题

什么意思?搂住想做什么?

什么啊！！！不知道！！！！

不在子进程中执行只能在当前进程中执行，那么 Unix/Linux 系统的 exec 族函数可以满足你的要求。但是，你的进程也就到此结束了。

是这样的，我需要做一个监控程序。监控我的程序是否正常。我就在unix下做了一个server，端口为9010。然后在windows下做了client。程序的效果达到了，是可以监控程序是否正常，但是从客户端启动的程序都带有9010端口。所以服务器重启的时候发现9010端口已经被监听。我想解决这个问题。就发了上面的帖子。没有说清楚，对不起大家。

try deamon

你的client怎么会占用server的9010端口？就算占用了重启server前把端口关了不就行了。

这里我改成单进程了
