Re: [Boost-users] Thread safety in Boost msm

Hi,

I am new to boost meta state library. I am building one app, where I have to use msm.

My application has two threads, where they use same msm object as a shared resources.

Now will the msm be thread safe if both threads call process_event on the same msm object?

Any idea is welcome.

Thanks,

Hi, msm is as thread-safe as a STL container: it's not. Different threads should not call process_event on the same state machine object. This means you'll have to serialize your calls to the object through a synchronization mechanism. HTH, Christophe
