std::ssize() in C++20 -- by Bartlomiej Filipek

std::ssize() in C++20

by Bartlomiej Filipek

From the article:

In this article, I’ll show another technique that avoids mixing signed and unsigned types.

In my article Integer Conversions and Safe Comparisons in C++20 we learned about cmp_* integer comparison functions that allow us to compare various types of integer types. The functions are safe because they help with mixing signed and unsigned types. In C++20, there’s another handy feature: the non-member std::ssize() function that returns a signed number of elements in a container.

Let’s see how to use it. ...

Enhance application security with FORTIFY_SOURCE -- Siddharth Sharma

Improving safety and security in GCC:

Enhance application security with FORTIFY_SOURCE

by Siddharth Sharma

From the article:

The FORTIFY_SOURCE macro provides lightweight support for detecting buffer overflows in various functions that perform operations on memory and strings. Not all types of buffer overflows can be detected with this macro, but it does provide an extra level of validation for some functions that are potentially a source of buffer overflow flaws. It protects both C and C++ code. ...

CppCon 2022 endnote video posted: "Can C++ be 10x simpler and safer ... ?" -- Herb Sutter

The second video from CppCon 2022 has now been posted:

CppCon 2022 talk is online: “Can C++ be 10x simpler & safer ... ?”

by Herb Sutter

From the post:

It was great to see many of you at CppCon, in person and online! It was a really fun conference this year, and the exhibitor hall felt crowded again which was a good feeling as we all start traveling more again.

The talk I gave on Friday is now on YouTube. In it I describe my experimental work on a potential alternate syntax for C++ (aka ‘syntax 2’ or Cpp2 for short) and my cppfront compiler that I’ve begun writing to implement it...

Opening 2022 Keynote: Bjarne Stroustrup, prerelease

From the article:

CppCon 2022 is in midweek and so much has happened thus far in Aurora, Colorado!

Along with great talks from C++ experts, we’ve had social events and panels, including our annual Committee Fireside Chat where attendees had the opportunity to hear directly from C++ standard committee members.

CppCon wouldn’t be the same though without an opening keynote from C++’s creator, Bjarne Stroustrup. This year Bjarne’s focus was on using C++ in Constrained Environments.

This video is in “prerelease” and cannot be found directly on our YouTube channel, instead we are providing a direct link here only! Feel free to share this with colleagues and friends and impress them with your insider access ��

Microsoft C++ team at CppCon 2022

by Sy Brand

From the article:

The Microsoft C++ team has an exciting lineup of sessions at CppCon 2022. Many of us will also be present at our team’s booth in the main hall for the first two days of the conference. Come say hi and let us know if you have any questions about our talks, products, or anything else! You can also join the #visual_studio channel on the CppCon Discord to talk to us (note: to join, head to #directory channel first, and check the checkbox next to “Visual Studio” box).

We’re also running a survey on the C++ ecosystem. If you have a moment, please take our survey, it’s quick.

Here’s the lineup: ...

Integrating C++ header units into Office using MSVC (1/n) - Cameron DaCamara and Zachary Henkel

A new post about modules, and see the related talk today at CppCon:

Integrating C++ header units into Office using MSVC (1/n)

by Cameron DaCamara and Zachary Henkel

From the article:

C++20 has had a lot to offer and one feature in particular requires the most thought of all when integrating into our projects: C++ modules (or C++ header units in this particular case). In this blog we will show a real world case of integrating a new C++20 feature into a large codebase that we might all be familiar with. ... This blog is the first in a series detailing experiences in integrating header units into the Office codebase.
