对于Android的网络通讯性能的提高,我们可以使用Java上高性能的NIO (New I/O) 技术进行处理,NIO是从JDK 1.4开始引入的,NIO的N我们可以理解为Noblocking即非阻塞的意思,相对应传统的I/O,比如Socket的accpet()、read()这些方法而言都是阻塞的。 NIO主要使用了Channel和Selector来实现,Java的Selector类似Winsock的Select...
按照这个定义,之前所述的blocking IO,non-blocking IO,IO multiplexing都属于synchronous IO。 有人会说,non-blocking IO并没有被block啊。这里有个非常“狡猾”的地方,定义中所指的”IO operation”是指真实的IO操作,就是例子中的recvfrom这个system call。non-blocking IO在执行recvfrom这个system call的时候,如果k...

在Python中,使用fcntl模块可以实现对文件描述符的非阻塞I/O控制。通过将文件描述符设置为非阻塞模式,可以确保I/O操作不会阻塞程序的执行。当需要进行非阻塞读取时,如果没有数据可用,read操作会立即返回并抛出OSError或BlockingIOError异常。这样程序就可以根据实际需求来处理这些异常情况。
