[Boost-users] [atomic] When to load/store

mwpowell...@gmail.com (Michael Powell) — Wed, 22 May 2013 15:04:39 UT

Hello,

I have some thread synchronization to do, probably will end up using
some sort of internally synchronized cancelation or other state to
message between parent and child thread.

If the state uses boost::atomic<bool> _canceled, for instance, how do
I go about setting/getting the value? I am assuming that we do

Hi,

Is there a way to manually set the next state for the state machine.
I have an orthogonal region defined for handling errors, where Error is an
interruptible state.

Okay, so without starting a flame war, because that is not my

Hi,

There is a severe bug in packaged_task constructor when compiling in

a regression, this have never worked.

Until I find a fix, the packaged_task could be used only with free

[Boost-users] [accumulator] with complex domain model

Hello,

We've got a complex domain model which must be accumulated and
eventually averaged together. I am already overloading the operators
for that model.

We could roll our own with just the operators we'll need to
accommodate, like +, +=, /, etc, but would like to take a gander at
Boost.Accumulator first. Would be much better, obviously, rather than

silha...@fel.cvut.cz (Petr Silhavik) — Wed, 15 May 2013 06:20:50 UT

Hi,

I have implemented timers for library Boost Statechart. It was tested
only on Linux because it uses POSIX threads. It is extension that
replaces fifo_scheduler and fifo_worker with only one class Scheduler.
That means that it is suitable only for asynchronous state machines.
