The return value of the returned HRESULT is one of the following:

Return value	Meaning
S_OK	Success.
STG_E_INSUFFICIENTMEMORY	Out of memory.

E_INVALIDARG	One or more of the arguments is invalid.

Comments

The index specifies the order of the variables. The first variable has an index of zero. ICreateTypeInfo::AddVarDesc returns an error if the specified index is greater than the number of variables currently in the type information. Calling this function does not pass ownership of the VARDESC structure to ICreateTypeInfo. The instance field (oInst) of the VARDESC structure is ignored. This attribute is set only when ICreateTypeInfo::LayOut is called. Also, the member ID fields within the VARDESCs are ignored unless the TYPEKIND of the class is TKIND_DISPATCH.

Any HREFTYPE fields in the VARDESC structure must have been produced by the same instance of ITypeInfo for which AddVarDesc is called.

AddVarDesc ignores the contents of the idldesc field of the ELEMDESC.
