/*
|
|
* 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.
