NetworkManager/src

src/

Most of the subdirectories are static helper libraries, which get linked into one of the final build artifacts (like libnm, nmcli or NetworkManager). Static libraries are internal API.

The only public API is libnm, which is a shared library provided client implementations.

Our own clients (like nmcli and nmtui) also use libnm, the shared library. But they also use additional static helper libraries.

The daemon statically links against a part of libnm, the part that provides connection profiles. That is libnm-core. libnm-core is thus statically linked with libnm and the daemon. It does not get linked by clients that already link with libnm (like nmtui).
