/*
* A sample program demonstrating how to use _CRT_fmode to change the default
* file opening mode to binary AND change stdin, stdout and stderr. Redirect
* stdout to a file from the command line to see the difference.
*
* Also try directing a file into stdin. If you type into stdin you will get
* \r\n at the end of every line... unlike UNIX. But at least if you
* redirect a file in you will get exactly the characters in the file as input.
*
* THIS CODE IS IN THE PUBLIC DOMAIN.
