我已撰写了一个服务器方案,通过使用叉(k)处理多个客户。 我有信号手,必要时进行错误检查,一切都正确发挥作用。 我已设立这样的机构,即如果客户离职,服务器应停止接受连接,让开户客户完成通信,一旦所有客户关闭,就关闭。 为了做到这一点,凡进入戒酒场时,我有一只旗帜。 由于每个儿童进程中的变量只是这一进程,而且不影响其他儿童进程或家长进程,我可以随时了解何时确定国旗。 在我的信号手里,我正在检查。
if( count == 0 && flag == 0)
//close server and exit program
这些数字是开放的客户数量,在关闭之后,其数量显然为零(为保证正确而核对错误)。 是否有任何人知道我可以创造旗帜,可以在一个客户中设定,每个客户都拥有同样的价值? 如果是这样的话。 我在C处穿着。
你们需要安装一个服务器,供每个人发言,他将向所有客户进行广播,以更新用户,但从根本上来说,没有很多复杂因素,无法说话并追踪所有其他客户,这是一个挑战。
这还将成为不同客户之间的路线和交通信息的地方。
希望这一光辉。
接收<条码>的受害儿童程序 指挥需要发出信号(例如<代码>)。 SIGUSR1 为此,我不建议<代码>SIGTERM,除非您将尽快关闭所有客户,并且请父母在its<>><>getpid ( some处)。)
有许多IPC机制可以这样做......尤其要记住ema。 你们可以产生一套两条ema的恐惧感,用一种来计算你们的孩子,一种用于你的旗帜。 当你开始方案时,客户的计数将初步定为零,而空旗将先入。 每一名儿童一开始,就应当加上一对客户的计算......,并在离开时减去。 当客户接受军阀指挥时,该旗帜就等于零。 主要方案将知道,当两只烟雾达到零时,什么都做了。
或者(如果可能的话),你仅可以开始读写,而不是启动程序,并使用2个全球<编码><<>int>,>>> 和flag,以及保护这些内容的全球交换标准。 在不需要大量校对通信的情况下,透镜APIC就很容易用于简单内容,而造面比fork+exec更快。
