The thermal framework implements a netlink notification mechanism to be used by the userspace to have a thermal configuration discovery, trip point changes or violation, cooling device changes notifications, etc... This library provides a level of abstraction for the thermal netlink notification allowing the userspace to connect to the notification mechanism more easily. The library is callback oriented.
