Introduction & Design Goals

cppzmq is a C++ binding for libzmq. It has the following design goals:

• cppzmq maps the libzmq C API to C++ concepts. In particular:
  • it is type-safe (the libzmq C API exposes various class-like concepts as void*)
  • it provides exception-based error handling (the libzmq C API provides errno-based error handling)
  • it provides RAII-style classes that automate resource management (the libzmq C API requires the user to take care to free resources explicitly)
• cppzmq is a light-weight, header-only binding. You only need to include the header file zmq.hpp (and maybe zmq_addon.hpp) to use it.
• zmq.hpp is meant to contain direct mappings of the abstractions provided by the libzmq C API, while zmq_addon.hpp provides additional higher-level abstractions.
