Re: [Boost-users] Assigning to a boost::asio::ssl::context while asynchronous operations are using it

Now I want to be able to load a new certificate without restarting the process (minimizing downtime). For this I have implemented a signal handler listening to SIGUSR1. This handler constructs a new ssl context and then move-assigns it to the ssl context variable in the main function.

Please notice that only syscalls marked as async-signal-safe may be used within a signal handler. Memory allocation is not async-signal-safe.
