/* In this article, I will explain how to spawn a console application
* and redirect its standard input/output using anonymous pipes. An
* anonymous pipe is a pipe that goes only in one direction (read
* pipe, write pipe, etc.). Maybe you are asking, "why would I ever
* need to do this sort of thing?" One example would be a Windows
* telnet server, where you spawn a shell and listen on a port and
* send and receive data between the shell and the socket
* client. (Windows does not really have a built-in remote
* shell). First, we should talk about pipes. A pipe in Windows is
* simply a method of communication, often between process. The SDK
* defines a pipe as "a communication conduit with two ends;
a process
* with a handle to one end can communicate with a process having a
* handle to the other end." In our case, we are using "anonymous"
* pipes, one-way pipes that "transfer data between a parent process
* and a child process or between two child processes of the same
* parent process." It's easiest to imagine a pipe as its namesake. An
* actual pipe running between processes that can carry data. We are
* using anonymous pipes because the console app we are spawning is a
* child process. We use the CreatePipe function which will create an
* anonymous pipe and return a read handle and a write handle. We will
* create two pipes, on for stdin and one for stdout. We will then
* monitor the read end of the stdout pipe to check for display on our
* child process. Every time there is something availabe for reading,
* we will display it in our app. Consequently, we check for input in
* our app and send it off to the write end of the stdin pipe. */
