A cross-platform event library where publishers and subscribers can span processes, platforms, devices, and networks.
If you need a C API for interprocess communication without all the IPC portability wrangling, checkout the ubiquitous libevent. It is probably already running on your machine. If you want a reactor-based implementation in C++, Boost ASIO is good too.
If you need simple IPC with many:many publishers:subscribers and familiar C++ syntax, wasl can help. It abstracts away the low-level socket details and does its best to stay out of your way.
