variant_get_type — Returns the type of a variant object
variantThe variant object.
This function returns an integer value that indicates the type of
variant, which can be an instance of
COM, DOTNET or
VARIANT classes. The return value can be compared
to one of the VT_XXX constants.
The return value for COM and DOTNET objects will usually be
VT_DISPATCH; the only reason this function works for
those classes is because COM and DOTNET are descendants of VARIANT.
