Its README says the project grew out of concepts developed in the ZeroMQ Guide and aims to wrap the core ZeroMQ API in shorter, more readable application semantics. ### Adoption history CZMQ became part of the standard ZeroMQ packaging stack because C applications and language bindings could depend on higher-level socket, certificate, actor, and system helpers instead of writing directly against libzmq primitives. ### How it is used Developers use CZMQ as a C library layered on libzmq, commonly through package-manager development packages. The README documents building against libzmq, package-manager installation paths, zsock, zauth, zcert, zactor, and the zmakecert helper for CURVE certificates. ### Why package nerds care For package nerds, CZMQ is one of the classic split-library cases: libzmq is the core, CZMQ is the high-level C convenience layer, and both tend to appear together in Unix package repositories for messaging software. ### Timeline - 2011: CZMQ repository created. - 2016: v4.0.2 release published. - 2021: v4.2.1 release published. ### Related projects - CZMQ is closely tied to libzmq, the ZeroMQ Guide, ZeroMQ security mechanisms such as CURVE, and bindings built on top of the C layer. ### Sources -
