Wine API: VarMul

NAME

VarMul (OLEAUT32.156)

SYNOPSIS

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

DESCRIPTION

Multiply two variants.

PARAMS

`left`	[In]	First variant.
`right`	[In]	Second variant.
`result`	[Out]	Result variant.

RETURNS

Success: S_OK.

Failure: An HRESULT error code indicating the error.

NOTES

Native VarMul up to and including WinXP doesn't like I1, UI2, UI4, UI8, INT and UINT as input variants. But it can multiply apples with oranges.

Native VarMul 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.
