L_INT pEXT_CALLBACK YourFunction (nKey, uHotKeyModifiers, pUserData)
Key code for activation key.
Modifier keys used with nHotKey. Possible values are listed below and may be combined.
| MOD_ALT | Alt Key pressed. |
|---|---|
| MOD_CONTROL | Control key pressed. |
| MOD_SHIFT | Shift key pressed. |
| 0 | No modifier key was pressed. |
Void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of the calling function.)
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
Use this callback function to receive notification that the capture HotKey has been pressed by the user. Set this callback using L_CaptureSetKeyPressCallback.
If you do not wish to process the pressed HotKey + Modifiers combination, return ERROR_USER_ABORT.
For an example, refer to L_CaptureSetKeyPressCallback.
