Yes, if you need low-level library introspection on Linux or macOS. The package is lightweight, has no dependencies, and carries a permissive license. The aging maintenance is a minor concern—the last release was 575 days ago—but the code is stable and the repository is not archived. Install it if you have a specific need for dlinfo; otherwise, it's a niche tool.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; only works on Linux and macOS systems where libc's dlinfo or dyld_find is available.
- Low install friction with no runtime dependencies.
- Maintenance is aging—last release was 575 days ago, though the repository remains active and the package is marked Production/Stable.

What it is and what it does
dlinfo is a thin Python wrapper around libc's dlinfo function (and macOS's dyld_find), enabling you to inspect runtime properties of dynamically loaded libraries. It wraps low-level C library introspection behind a simple Python interface, so you can query things like the file path of a loaded shared library without calling dlinfo directly through ctypes.
The package has no runtime dependencies and installs as a pure Python wheel. It's intended for developers who need to examine loaded libraries at runtime—for example, to verify which version of a system library is in use, or to locate library files for further inspection. The interface is minimal: you create a DLInfo object from a ctypes library handle and access properties like path.
Use it for
- Verify which version of libc or another system library is currently loaded in your Python process.
- Locate the file path of a dynamically loaded library for debugging or introspection purposes.
- Build tools or diagnostics that need to report on runtime library dependencies and their locations.
- Cross-platform library inspection on Linux and macOS without writing platform-specific C code.
