Re: [paho-dev] In asynchronous mode questions.

Hi Laurent,

the callback functions run in the parallel thread.   You can use the standard pthread API for semaphores, yes. 

Why do you say that no pthread link is required?  The Linux build for the C library has a link to pthread.

Hello,

As per the documentation, http://www.eclipse.org/paho/files/mqttdoc/Cclient/async.html, the communication handling is done in a parallel thread. But does the callback function running in this parallel thread or in the main process ?

If, as I think, it is in the parallel thread, how can I use semaphores ? Using standard pthread API ? I wonder as there is no explicit link to phread required.

Thanks

Laurent
