RtlLongLongMult function (ntintsafe.h)

Multiplies one value of type LONGLONG by another.

Syntax

NTSTATUS RtlLongLongMult(
  [in]  LONGLONG llMultiplicand,
  [in]  LONGLONG llMultiplier,
  [out] LONGLONG *pllResult
);

Parameters

[in] llMultiplicand

The value to be multiplied by llMultiplier.

[in] llMultiplier

The value by which to multiply llMultiplicand.

[out] pllResult

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.
