Collapse All

Clears the data from a built-in Variant type.

Pascal
procedure VarDataClear(var Dest: TVarData);
C++
__fastcall VarDataClear(TVarData Dest);
Description

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.
