I was using ACE library for multithreading in c++. Totally unaware about how to use concept with direct c++ libraries and developed laziness due to fear of new syntaxes . After going through your playlist felt like nirvana :) . You are doing awesome work. Keep doing. Keep enlighten people.

Hi Rupesh, Your concept explanation is good, but the only thing I feel missing in the videos is that real-time example of the concept and its advantages over traditional concepts if that gets added up it would really help the viewers to understand the concept better
like for example :
"when returning, or when an exception is thrown. You should always prefer to use lock_guard or unique_lock instead of using mutex:: lock()"
Example:
================== Traditional Lock Problem =================
std:: mutex m1; // Mutex Declaration
some Func( ) {
try
{
m1.lock(); // Lock Aquired
Tcp/Udp request call(); or // If any of these call fails then "lock remains"
SomeDllCall() or
ThirdPartyLibraryCall()
m1.Unlock(); // Lock Released
}
catch(Exception Handler e)
Cout

The real power of lock_guard as you mentioned in the comments is in RAII. I was asked RAII in an interview but I did not know :(. I guess this deserves a seperate video like you awesome video on RVO and NRVO.

[@CppNuts]

Will try, now i am so much busy these day!!

[@MrMaddieDawson]

RAII - Resource Acquisition Is Initialization!

I am here to know when to use lock_gurad vs unique lock partially i got answer will see next video on unique lock thank you ::)

[@CppNuts]

Great 👍

[@vaibhavgupta8048]

what if any exception occurs in the for loop , how lock_guard will be advantageous ..

[@CppNuts]

It will release lock while stack unwinding.

[@CppNuts]

[@kevin-ru6oe]

Are your videos based on a book? I would like to know the name of that book. Or if you can recommend me a book to learn about concurrency problems, threads and mutual exclusion, I would thank you.

[@CppNuts]

No my videos are not from any book, they are from my heart. ❤️
And I have never read any book for c plus plus.
Thanks man..
