|
|
* 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).
