This code integrates libmnl (minimal netlink library) into the osmocom select loop abstraction.
It allows other osmocom libraries or application code to create netlink sockets and subscribe to netlink events via libmnl. The completion handler / callbacks are dispatched via libosmocore select loop handling.
void osmo_mnl_destroy | ( | struct osmo_mnl * | omnl | ) |
destroy an existing osmocom-wrapped mnl netlink socket: Unregister + close + free.
[in] | omnl | osmo_mnl socket previously returned by osmo_mnl_init() |
