QMutex and unique_lock ?

[SPlatten]

I'm replacing mutex references in a project previously using boost for:

boost::mutex and boost::recursive_mutex

There are also several instances using:

std::unique_lock<boost::mutex> lock(&mutex);

https://en.cppreference.com/w/cpp/thread/unique_lock

Is there an equivalent implementation for achieving the same using a QMutex ?

@jsulm , I see what there are references to recursive, but no reference to unique anywhere.

@SPlatten said in QMutex and unique_lock ?:

I see what there are references to recursive, but no reference to unique anywhere.

Don't get hung up on the name. https://en.cppreference.com/w/cpp/thread/unique_lock has no reference to "unique" anywhere either (except for the name of the class)!

• A std::unique_lock is simply a std::lock_guard that can be unlocked/relocked.
• A QMutexLocker is like a std::lock_guard that can be unlocked/relocked.

Just use QMutexLocker the same way you'd use std::unique_lock.

@JKSH Thanks
