You could then use the setmode() function (in the Microsoft C run-time
library) to change the mode ...

#include <stdio.h>
#include <fcntl.h>

extern int errno;

...
	if(setmode(fileno(stdin), O_BINARY) == -1)
		printf("error = %d when changing mode to binary\n", errno);

As described in the "Run-time Library Reference Manual", setmode() changes
the mode (text or binary) of an already open file.
