/**
INTN Addition
Performs the requested operation using the input parameters into a value
specified by Result type and stores the converted value into the caller
allocated output buffer specified by Result. The caller must pass in a
Result buffer that is at least as large as the Result type.
If Result is NULL, RETURN_INVALID_PARAMETER is returned.
If the requested operation results in an overflow or an underflow condition,
then Result is set to INTN_ERROR and RETURN_BUFFER_TOO_SMALL is returned.
@param[in] Augend A number to which addend will be added
@param[in] Addend A number to be added to another
@param[out] Result Pointer to the result of addition
@retval RETURN_SUCCESS Successful addition
@retval RETURN_BUFFER_TOO_SMALL Overflow
