RtlUIntPtrMult function (ntintsafe.h)

  • Article

Multiplies one value of type UINT_PTR by another.

Syntax

NTSTATUS RtlUIntPtrMult(
  [in]  UINT_PTR uMultiplicand,
  [in]  UINT_PTR uMultiplier,
  [out] UINT_PTR *puResult
);

Parameters

[in] uMultiplicand

The value to be multiplied by uMultiplier.

[in] uMultiplier

The value by which to multiply uMultiplicand.

[out] puResult

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.

This function uses the following alternate name:

  • RtlUIntPtrMult
  • RtlULongPtrMult
  • RtlDWordPtrMult
  • RtlSizeTMult
  • RtlSIZETMult
  • RtlDWordLongMult
  • RtlULong64Mult
  • RtlDWord64Mult
  • RtlUInt64Mult
