NAME¶

VarXor (OLEAUT32.167)

SYNOPSIS¶

HRESULT VarXor
(
LPVARIANT pVarLeft,
LPVARIANT pVarRight,
LPVARIANT pVarOut
)

DESCRIPTION¶

Perform a logical exclusive-or ( XOR) operation on two variants.

PARAMS¶

pVarLeft [In] First variant. pVarRight [In] Variant to XOR with pVarLeft. pVarOut [Out] Destination for XOR result.

RETURNS¶

Success: S_OK. pVarOut contains the result of the operation with its type taken from the table below). Failure: An HRESULT error code indicating the error.

NOTES¶

- Neither pVarLeft or pVarRight are modified by this function. - This function does not process by-reference variants. - Input types of VT_BSTR may be numeric strings or boolean text. - The type of result stored in pVarOut depends on the types of pVarLeft and pVarRight, and will be one of VT_UI1, VT_I2, VT_I4, VT_I8, VT_BOOL, or VT_NULL if the function succeeds. - Type promotion is inconsistent and as a result certain combinations of values will return DISP_E_OVERFLOW even when they could be represented. This matches the behaviour of native oleaut32.
