- Simulation of a 3D visualizer
change
- 使用系统调用pipe()建立一条管道，系统调用fork()分别创建两个子进程，它们分别向管道写一句话，如： Child process1 is sending a message! Child process2 is sending a message! 父进程分别从管道读出来自两个子进程的信息，显示在屏幕上。两个子进程并发执行。 实现管道的互斥使用。当一个子进程正在对管道进行写操作时，另一个欲写入管道的子进程必须等待。 使用系统调用lockf(fd[1],1,0)实

epollexample
- epoll最大的好处在于它不会随着监听fd数目的增长而降低效率,epoll使用实例-epoll biggest advantage is that it does not increase with the number of listening fd reduced efficiency, epoll use cases
adb_client
- connect to adb, connect to the named service, and return a valid fd for interacting with that service upon success or a negative number on failure
fd-safer
- Return a safer copy of a file descr iptor.
get_console
- Get an fd for use with kbd/console ioctls Source Code for Linux.
IO-(2)
- *使用select函数可以以非阻塞的方式和多个socket通信。程序只是演示select函数的使用，即使某个连接关闭以后也不会修改当前连接数，连接数达到最大值后会终止程序。 1. 程序使用了一个数组fd，通信开始后把需要通信的多个socket描述符都放入此数组 2. 首先生成一个叫sock_fd的socket描述符，用于监听端口。 3. 将sock_fd和数组fd中不为0的描述符放入select将检查的集合fdsr。 4. 处理fdsr中可以接收数据的连接。如果是sock_fd，
trans_fd
- Fd transport layer. Includes deprecated socket layer.
fd
- New file layout: Now the ioctl definitions immediately follow the definitions of the structures that they use.
lproc_mdc
- This works for either broadcast or unicast to a single fd.
