| [in] idSensor |
The ID of the fingerprint reader that raised the event. |

C++
typedef void CALLBACK GRCAP_FINGER_EVENT_PROC(char* idSensor, GRCAP_FINGER_EVENTS event);
Delphi
GRCAP_FINGER_EVENT_PROC = Procedure(idSensor: Pchar; event: GRCAP_FINGER_EVENTS); stdcall;
C++
void FingerEventHandler(char* idSensor, GRCAP_FINGER_EVENTS event) {
// Just signals that a finger event occurred.
WriteEvent(idSensor, event);
}
Delphi
// This Function is called every time a finger is placed or removed //from reader.
Procedure FingerCallback(idSensor: Pchar; event: GRCAP_FINGER_EVENTS); stdcall;
Begin
// Just signals that a finger event occurred.
WriteEvent(idSensor, event);
End;
