Description

Clears the data from a built-in Variant type.

Call VarDataClear from the implementation of a TCustomVariantType descendant to clear the data in the TVarData record of a Variant. Do not use VarDataClear as the entire implementation of the Clear method, as this will lead to a circular reference.

Dest is the TVarData record of a Variant type, and returns the result after clearing the data.
