Description
TVarDispProc defines a pointer to a procedure used as support for IDispatch-based Automation.
In Delphi, TVarDispProc is a pointer to a routine that is called to execute methods (or access properties) of an interface that is assigned to a Variant. TVarDispProc is used in the Variants unit to control how Variants execute methods when a value of the Variants is an interface.
