RtlULongMult function (ntintsafe.h)

  • Artikel

Multiplies one value of type ULONG by another.

Syntax

NTSTATUS RtlULongMult(
  [in]  ULONG ulMultiplicand,
  [in]  ULONG ulMultiplier,
  [out] ULONG *pulResult
);

Parameters

[in] ulMultiplicand

The value to be multiplied by ulMultiplier.

[in] ulMultiplier

The value by which to multiply ulMultiplicand.

[out] pulResult

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

Return value

Returns STATUS_SUCCESS if the operation is successful.

See the implementation of this helper function in ntintsafe.h in the WDK for possible error return values.

Remarks

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