SYNOPSIS

HRESULT VarAdd
 (
  LPVARIANT left,
  LPVARIANT right,
  LPVARIANT result
 )

DESCRIPTION

Add two variants.

right [In] Second variant.

NOTES

Native VarAdd up to and including WinXP doesn't like I1, UI2, UI4, UI8, INT and UINT as input variants.

Native VarAdd doesn't check for NULL in/out pointers and crashes. We do the same here.

FIXME

Overflow checking for R8 (double) overflow. Return DISP_E_OVERFLOW in that case.
