Syntax

Parameters
None
Return value
Returns true if a key has been pressed.
| Value | Description |
|---|---|
| TRUE | The Key is pressesed. |
| FALSE | The key is not pressed. |
Remarks
Use the Idle function when kbhit() is used to wait for keyboard input.
When a user wants to wait for a key press, it is advised to call ResetKey function first, in order to be sure that a previous key, still in the keyboard buffer, doesn't cause kbhit() to return with TRUE.
Please note that the Shift key and Power key cannot be judged for pressing.
