RtlULongPtrMult function (ntintsafe.h)

  • Article

Multiplies one value of type ULONG_PTR by another.

Syntax

NTSTATUS RtlULongPtrMult(
  ULONG_PTR ulMultiplicand,
  ULONG_PTR ulMultiplier,
  ULONG_PTR *pulResult
);

Parameters

ulMultiplicand

The value to be multiplied by Multiplier.

ulMultiplier

The value by which to multiply Multiplicand.

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.
