imagine you're running your program via telnet or ssh. In this case,
"real" console and your program may be on different hosts! so i doubt
there's a way to "break the pipe"

to choose at compile time, you can use ifdefs.

#ifdef WIN32_CONSOLE
  /* win32-style console handling code */
#else
  /* unix-style console handling code */
#endif

at runtime -- isatty(), as Troy suggested.
