The os.Create function creates or truncates the specified file. It is truncated if the file already exists. The file is generated in mode 0666 if it doesn't already exist. The example makes an empty file: packagemainimport("fmt""log""os")funcmain(){file,err:=os.Create("helloGoLinuxCl...

在go的IO中,除了io 、os等包,我们还有strings 、 bytes 、bufio等实现IO读写,这其中有些实现了io.Reader,有些同时实现了io.Reader和io.Writer接口。接下来我们一个个看相关的使用。 1.strings 在strings包中,只实现了Reader,我们看看其代码: // 实现的 reader ...
在内核里,一切皆文件。所以,epoll向内核注册了一个文件系统,用于存储上述的被监控socket。当你调用epoll_create时,就会在这个虚拟的epoll文件系统里创建一个file结点。当然这个file不是普通文件,它只服务于epoll。 epoll在被内核初始化时(操作系统启动),同时会开辟出epoll自己的内核高速cache区,用于安置每一个我们想监...
