Operation cancelling and std::fstream
In the previous post we have sketched out the view that error handling is about expressing the success dependency between operations. I have also indicated the guideline “destructors only for releasing resources”. In this post we are going to see … Continue reading

Handling errors is canceling operations
I actually covered this topic before, in this post, but given my recent experience I feel it needs reiterating and a bit of restructuring. It boils down to the observation that any error handling I have encountered — be it … Continue reading

Destructors — 2 use cases
In this post I want to describe an interesting observation: programmers generally use destructors for two purposes. One is fairly obvious: releasing resources; the other — not necessarily so.
noexcept — what for?
In this post I would like to share my observation on where using noexcept really adds value. It is less often than what one might expect, and it does not have that much to do with throwing or not throwing … Continue reading

Find the bug — comments
In response to the previous post, I have received a bunch of very useful comments. I would like to share them here.
noexcept destructors
The goal of this post is to show one — fairly small — backwards incompatibility in C++11. It shows how noexcept exception specifications are implicitly generated for your destructors. In short, the following program used to run successfully in C++03 … Continue reading
C++’s best feature
Update. My remark on exceptional life-time of temporaries in array initialization was incorrect. This part is now fixed. I also included some essential information, as suggested by Herb Sutter. C++, if you want to learn all of it, is big, … Continue reading
(Not) using std::thread
This post is about std::thread but not about threads or multi-threading. This is not an introduction to C++ threads. I assume that you are already familiar with Standard Library components thread and async. I encountered a couple of introductions to … Continue reading
Using std::terminate
In this article we are going to see what happens when your program calls std::terminate. If you think it simply terminates the program, you may find it interesting that it is not always so, and the function may be used … Continue reading
