As is, the code should be printing a line number yet it doesn’t (in 17.7.3 and 17.8.0 Preview 1.0). You can make one of the following adjustments to make the destructor be called property: changeconstexprsecure_location_t toconstevalsecure_...
Example:It is true thatreinterpret_castis not portable because of one reason - byte order (endianness). But this is often surprisingly the best reason to use it. Let's imagine the example: you have to read binary 32bit number from file, and you know it is big endian. Your code has t...
Each window takes up system resources, so an application should not use child windows indiscriminately. For best performance, an application that needs to logically divide its main window should do so in the window procedure of the main window rather than by using child windows....
The error message was: "the expression must have a constant value", which happened because PROTOBUF_FIELD_OFFSET internally uses reinterpret_cast, which is not allowed in a constexpr context in C++20. This limitation is due to the stricter compile-time evaluation rules introduced in the C++20...
There was a change in VS 2022 to make VS more compliant with the C++ standard and make std::mutex a constexpr. However, this causes problems if an older version of the runtime is loaded first - in ...

Today, I use kinect to record a video. And then I use Azure Kinect Viewer to check the depth(like figure in the below). But when I use ffmpeg to extract all the depth map, I found that all of that are black. I don't know why? This is my cmd log: PS…
Resolve references in the body of an external method when it is accessed. One such case occurs when checking a call expression: if the callee contains return statements, we attempt to check them. Test: cd ../out && ninja tests tests/tests-u-runner/runner.sh --ets-cts --show-progress ...
