ULongPtrMult function (intsafe.h)

Multiplies one value of type ULONG_PTR by another.

Syntax

HRESULT ULongPtrMult(
  [in]  ULONG_PTR ulMultiplicand,
  [in]  ULONG_PTR ulMultiplier,
  [out] ULONG_PTR *pulResult
);

Parameters

[in] ulMultiplicand

Type: ULONG_PTR

The value to be multiplied by ulMultiplier.

[in] ulMultiplier

Type: ULONG_PTR

The value by which to multiply ulMultiplicand.

[out] pulResult

Type: ULONG_PTR*

A pointer to the result. If the operation results in a value that overflows or underflows the capacity of the type, the function returns INTSAFE_E_ARITHMETIC_OVERFLOW and this parameter is not valid.

Return value

Type: HRESULT

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

This is one of a set of inline functions designed to provide arithmetic operations and perform validity checks with minimal impact on performance.
