history
Project history and usage
CZMQ is the high-level C binding for ZeroMQ, packaging a friendlier C API, helper classes, actors, and command-line utilities around the lower-level libzmq messaging library.
Project history
The CZMQ repository was created in 2011. 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.
