RtlULongAdd function (ntintsafe.h)

Adds two values of type ULONG.

Syntax

NTSTATUS RtlULongAdd(
  [in]  ULONG ulAugend,
  [in]  ULONG ulAddend,
  [out] ULONG *pulResult
);

Parameters

[in] ulAugend

The first value in the equation.

[in] ulAddend

The value to add to ulAugend.

[out] pulResult

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.
