What are advanced features of std::condition_variable in C++11?

Can you explain the advanced features of std::condition_variable in C++11?

Sure! std::condition_variable allows threads to wait for certain conditions to be met. It provides advanced features like notifying one or all waiting threads, which helps in managing thread synchronization effectively.

How does it differ from using mutexes?

While mutexes are used to protect shared data, std::condition_variable is used for signaling between threads. It allows a thread to wait until a specific condition is true, which can lead to more efficient thread management.

Can you give an example of its usage?

Certainly! Here's a simple example: You can use std::condition_variable to make a producer thread wait until a consumer thread signals that data is available.

What are some common pitfalls when using condition variables?

Common pitfalls include forgetting to lock the mutex before waiting or notifying, and not handling spurious wakeups properly, which can lead to race conditions.
