Call-Back Function
9-3
Call-Back Function
When hotpad notification is performed via a call-back function, the application’s call-back function is
called by the DLL using the value of the
CallbackPointer
parameter (passed to the
SetHotpadNotification
function) as the call-back function address. The call-back function in your application must be declared in
the following manner:
void CALLBACK _export YourCallbackFunctionName ( )
KillHotpadNotification
This function disables hotpad notification for your application. Programs which have enabled hotpad
notification using
SetHotpadNotification
should call this function before exiting or when hotpad
notification is no longer desired. A prototype of this function is shown below:
BOOL KillHotpadNotification ( int
NotificationID )
You must pass the hotpad notification ID number that was returned by
SetHotpadNotification
as the
NotificationID
parameter. Note that this function disables hotpad notification for the calling application
only. Other applications which have enabled hotpad notification will continue to receive hotpad
notification. Return values for this function are as follows:
Return Value
Description
TRUE
Returned if the function is successful. Hotpad notification is disabled.
FALSE
Returned if the function fails.
This function will fail if the NotificationID parameter is not a valid hotpad
notification ID.
