i have to write some filter programs which must work for binary files, not
only for text ones.

i tried to open console into binary mode, but my program crashes when the
input isn't redirect from a file.

here an example:

test.c
-------
#include <stdio.h>
#include <fcntl.h>
main()
{
    char s[100];

    fflush(stdin);
    setmode(fileno(stdin), O_BINARY);

    gets(s);
    puts(s);
}

C:\> test < infile
ok! it displays it's first line

C:\> test
the program hangs!
nothing appears if i press some keys and CTRL-Break doesn't work!

i tried to add the line

    setmode(fileno(stdout), O_BINARY);

but the program continues to crash if invoked without redirection
