RtlDWordPtrAdd function (ntintsafe.h)
Adds two values of type DWORD_PTR.
Syntax
NTSTATUS RtlDWordPtrAdd(
[in] DWORD_PTR dwAugend,
[in] DWORD_PTR dwAddend,
[out] DWORD_PTR *pdwResult
);
Parameters
[in] dwAugend
The first value in the equation.
[in] dwAddend
The value to add to dwAugend.
[out] pdwResult
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.
