Description

Registers or deregisters a user-defined callback function that is called after the stretch command completes on an FGR instance. You can do post-processing on the edited FGR instance in the registered callback function.

The user callback function must be defined before calling the vfoPostStretchCBHandler function to successfully register it as a callback function.

Arguments

t_mode	Specifies mode to register or deregister a user-defined callback function. Valid values are: r: Registers the user-defined callback function. d: Deregisters an already registered user-defined callback function.
S_callbackFunction	Name or function symbol of a user-defined callback function.

Value Returned

t	The user callback function was registered or deregistered successfully.
nil	The user callback function could not be registered or deregistered.

Examples

Registers the user-defined callback function fixOrigin for post-stretch operation.

procedure(fixOrigin(inst)

                print("callback to do any post-processing on the FGR instance")

)

vfoPostStretchCBHandler("r" 'fixOrigin)

or

vfoPostStretchCBHandler("r" "fixOrigin")
