RtlUIntPtrAdd function (ntintsafe.h)

  • Article

Adds two values of type UINT_PTR.

Syntax

NTSTATUS RtlUIntPtrAdd(
  [in]  UINT_PTR uAugend,
  [in]  UINT_PTR uAddend,
  [out] UINT_PTR *puResult
);

Parameters

[in] uAugend

The first value in the equation.

[in] uAddend

The value to add to uAugend.

[out] puResult

A pointer to the sum. 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:

  • RtlDWordAdd
  • RtlUIntPtrAdd
  • RtlULongPtrAdd
  • RtlDWordPtrAdd
  • RtlSIZETAdd
  • RtlDWordLongAdd
  • RtlULong64Add
  • RtlDWord64Add
  • RtlUInt64Add
