 * Name: PDC_get_key
 *
 * Description:
 *   Get the next available key, or mouse event (indicated by a return of
 *   KEY_MOUSE), and remove it from the OS' input queue, if applicable. This
 *   function is called from wgetch(). This function may be blocking, and
 *   traditionally is; but it need not be. If a valid key or mouse event
 *   cannot be returned, for any reason, this function returns -1. Valid keys
 *   are those that fall within the appropriate character set, or are in the
 *   list of special keys found in curses.h (KEY_MIN through KEY_MAX). When
 *   returning a special key code, this routine must also set SP->key_code to
 *   true; otherwise it must set it to false. If SP->return_key_modifiers is
 *   true, this function may return modifier keys (shift, control, alt),
 *   pressed alone, as special key codes; if SP->return_key_modifiers is
 *   false, it must not. If modifier keys are returned, it should only happen
 *   if no other keys were pressed in the meantime; i.e., the return should
 *   happen on key up. But if this is not possible, it may return the
 *   modifier keys on key down (if and only if SP->return_key_modifiers is
 *   true).
