C++ From Scratch: std::mutex

[@ChrisCox-wv7oo]

Love the video series, really appreciate it. To add a little bit more detail about lock guard, and RAII... It's not just used to keep you protected in cases where you forget to unlock the mutex... It protects you specifically when you can't unlock the mutex, like when an exception is thrown. When an exception is thrown, the destructors of local variables are guaranteed to run. So the lock guard opens the mutex on destruction. The lock guard goes out of scope when an exception is thrown, or when local scope ends naturally (function return, block scope ends, etc).

I was very happy to land on this channel again. Your channel helped me a lot in the past with CUDA! Thanks a lot!

This is super helpful, I especially love that you are also showing the cpp reference on the side! Coming from an engineering & python background that page is a complete mystery for me. Thanks a lot for all you do! :D

great video! for the people who are confused as to why he initialized the lock_guard object inside the function instead of outside, the lock_guard object would destruct due to control going out of scope.

What a wonderful human being. Your videos are great and the explanations are easy to understand.

Nice, thank-you! I leanerd something new today - lockguard!

Another fun exercise for anyone passively watching, implement puts() by parallelizing putc().

I'm using VS 2022. Why my std::vector my_threads; has an error on jthread saying: namespace "std" has no member "jthread" ?

[@loftyTHEOWNER]

Solved! You have to use C++20. Right click on your project -> Properties -> C/C++ -> Language -> C++ Language Standard -> from the dropdown menu select the "ISO C++20 Standard" option.

Thanks for the video. I like your approach of teaching C++ and the focus on modern features. Do you know any similar resource to learn Rust?

[@NotesByNick]

Glad you have enjoyed the video - I'm afraid I do not (I have not worked with Rust to any meaningful degree). Cheers, --Nick

​@@NotesByNick don't fear, you are a man of steel, you won't rust😂

[@VoidloniXaarii]

Thank you! This was very helpful

[@ShubhamJha-v8r]

Nicely Explained. Keep up the good work.

Thanks, fella!
