VarNot(3w)
NAME
VarNot (OLEAUT32.174)
SYNOPSIS
HRESULT VarNot ( LPVARIANT pVarIn, LPVARIANT pVarOut )
DESCRIPTION
Perform a not operation on a variant.
PARAMS
pVarIn [In] Source variant.
pVarOut [Out] Destination for converted value.
RETURNS
Success: S_OK. pVarOut contains the converted value.
Failure: An HRESULT error code indicating the error.
NOTES
- Strictly speaking, this function performs a bitwise ones complement on the variants value (after possibly converting to VT_I4, see below). This only behaves like a boolean not operation if the value in pVarIn is either VARIANT_TRUE or VARIANT_FALSE and the type is signed.
- To perform a genuine not operation, convert the variant to a VT_BOOL
before calling this function.
- This function does not process by-reference variants.
- - The type of the value stored in pVarOut depends on the type of
pVarIn, according to the following table:
- Input Type Output Type
---------- -----------VT_EMPTY VT_I2
VT_R4 VT_I4
VT_R8 VT_I4
VT_BSTR VT_I4
VT_DECIMAL VT_I4
VT_CY VT_I4
(All others) Unchanged
