Question

In my application, threads can be interrupted with boost::thread::interrupt. I want to reuse interrupted thread, can I just catch boost::interrupted_exception, or it is ideologically incorrect?

Answer 1

I want to reuse interrupted thread

It looks like you can (emphasis added):

boost::thread_interrupted is just a normal exception, so it can be
caught, just like any other exception. This is why the “interrupted”
flag is cleared when the exception is thrown — if a thread catches and
handles the interruption, it is perfectly acceptable to interrupt it
again. This can be used, for example, when a worker thread that is
processing a series of independent tasks — if the current task is
interrupted, the worker can handle the interruption and discard the
task, and move onto the next task, which can then in turn be
interrupted. It also allows the thread to catch the exception and
terminate itself by other means, such as returning error codes, or
translating the exception to pass through module boundaries.
