Synopsis:
    #include <conio.h>
    int getch( void );

Description:
    The getch function obtains the next available keystroke from the
    console.  Nothing is echoed on the screen (the function  getche will
    echo the keystroke, if possible).  When no keystroke is available, the
    function waits until a key is depressed.

    The  kbhit function can be used to determine if a keystroke is
    available.

Returns:
    A value of EOF is returned when an error is detected; otherwise the
    getch function returns the value of the keystroke (or character).

    When the keystroke represents an extended function key (for example, a
    function key, a cursor-movement key or the ALT key with a letter or a
    digit), zero is returned and the next call to getch returns a value for
    the extended function.

Example:
    #include <stdio.h>
    #include <conio.h>

    void main()
      {
        int c;

        printf( "Press any key\n" );
        c = getch();
        printf( "You pressed %c(%d)\n", c, c );
      }
