Effective C + + study notes clause 29-31

Article 29: Work for exceptional safety is a worthwhile "review"

1, the exception security function even if an exception occurs will not disclose resources or allow any data structure corruption, such functions are divided into 3 possible guarantees: basic type, strong type, not throw abnormal type

2, "strong guarantee" can often be achieved through copying and swap, but not all functions can be realized or have practical significance.

3. The "Exception security guarantee" provided by the function is usually the most vulnerable to the "exception safety" of each function that it calls.
