* Child processes that use such C run-time functions as printf() and fprintf() can behave poorly when redirected.
* The C run-time functions maintain separate IO buffers. When redirected, these buffers might not be flushed immediately after each IO call.
* As a result, the output to the redirection pipe of a printf() call or the input from a getch() call is not flushed immediately and delays, sometimes-infinite delays occur.
* This problem is avoided if the child process flushes the IO buffers after each call to a C run-time IO function.
* Only the child process can flush its C run-time IO buffers. A process can flush its C run-time IO buffers by calling the fflush() function.
