SafeAdd
Adds two numbers in a way that protects against overflow.
template<typename T, typename U>
inline bool SafeAdd (
T t,
U u,
T& result
) throw ();
Parameters
[in] t
The first number to add. This must be of type T.[in] u
The second number to add. This must be of type U.[out] result
The parameter where SafeAdd stores the result.
Return Value
true if no error occurs; false if an error occurs.
Remarks
This method is part of SafeInt Library and is designed for a single addition operation without creating an instance of the SafeInt Class.
Hinweis
This method should only be used when a single mathematical operation must be protected. If there are multiple operations, you should use the SafeInt class instead of calling the individual stand-alone functions.
For more information about the template types T and U, see SafeInt Functions.
