C ++ std :: thread与C pthread_mutex_t组合

Question

Just a quick question on which I didn't find clear answer:

Is it completely safe to create C++ std::thread s, in which I use pthread_mutex_t for locking critical sections?

EDIT : Mutexes locks parts of code to be safe from race conditioning. So I think it should have nothing to do with the matter of choosing C or C++ threads.

Answer 1

Don't do it, that's what std::mutex 's are for, and if you want to further investigate you can google about all std::thread related things.

I consider it important to point out, that I have never used std::thread s in my life, but it's just a reasonable assumption that if there exists, std::thread , there must be a std::mutex , I typed std::mutex in google and the page in the link I posted in this answer appeared.

Answer 2

For portability, use std::thread and its associated structures like std::mutex . Minimize use of eg native handles etc. Using the std:: mechanisms also makes your code less buggy, by using RAII. Without it, even experienced programmers forget to unlock locks at eg exceptions.

But here is a question similar to yours: Is it safe to mix pthread.h and C++11 standard library threading features?

Answer 3

use std::mutex,

or, you can use std::atomic with std::thread

// std::atomic<UINT8> a;
thread t(f, std::ref(a));
t.detach();
