What is the difference between std::mutex and std::conditional_variable?

What is the difference between std::mutex and std::conditional_variable?

std::mutex is used for mutual exclusion, while std::conditional_variable is used for signaling between threads.

Can you give an example of how to use both in a program?

Sure! You can use std::mutex to protect shared data and std::conditional_variable to wait for a condition to be met before proceeding.

When should I use std::conditional_variable instead of just using std::mutex?

Use std::conditional_variable when you need to wait for a specific condition to be true, which allows for more efficient thread management.

Are there any performance considerations I should be aware of?

Yes, using std::conditional_variable can reduce busy-waiting and improve performance, especially in scenarios with many threads.
