libmodulesuname

Libmodulesuname is a cross-platform C library that provides a unified API for querying kernel module metadata alongside system identity information. The library merges data about currently loaded kernel modules with uname-style host data to support tools that diagnose, audit, or report on a system’s runtime configuration. It is intended for use by system administrators, packaging tools, and diagnostic utilities that must reflect both module state and host identity in a consistent way.

Key features include enumeration of loaded modules with per-module attributes such as name, version, license, author, size, and module dependencies; retrieval of uname data including system name, release, version, machine, and nodename; and thread-safe access with a simple, well-defined lifecycle. The library reads data from standard kernel interfaces where available, and gracefully handles environments with limited module information.

The API provides initialization and cleanup functions, module iteration callbacks or iterator objects, and accessors for module records and uname fields. Error reporting is standardized through return codes and an optional error string. The interface is designed to be portable across Unix-like platforms that expose module data through /proc, /sys, or equivalent interfaces.

Typical usage involves creating a context, enumerating modules, querying desired attributes, and releasing resources. Applications can format results for human readers or downstream tooling, and can export data in formats such as JSON or YAML through separate utilities.
