QFuture<void>::pause()

`QFuture<void>::pause()` is a member function in the Qt framework's `QFuture` class that is used to pause the execution of a running `QFuture` object.

A `QFuture` object represents a computation that can be executed asynchronously in a separate thread, and `pause()` can be used to temporarily stop the execution of the computation.

When `pause()` is called, the `QFuture` object will pause its execution at the next available opportunity, and will remain paused until `resume()` is called. During the paused state, the `QFuture` object will not consume any system resources, allowing other threads to run more efficiently.

Here's an example of how to use `pause()` and `resume()`:

// Create a QFuture object to execute a function asynchronously
QFuture<void> future = QtConcurrent::run(myFunction);

// Pause the execution of the future object
future.pause();

// Do some other work while the future is paused
// ...

// Resume the execution of the future object
future.resume();

Note that `pause()` and `resume()` are only available for `QFuture` objects that are created with the `QtConcurrent` framework. If you create a `QFuture` object manually, you will need to implement your own mechanism for pausing and resuming the computation.
