Detailed Description

Functions for starting and stopping subsystems.

Variable Documentation

subsystem_deinit_list

std::vector<void (*)()> hi::v1::detail::subsystem_deinit_list

inline

A list of deinit function to be called on shutdown.

subsystem_mutex

unfair_recursive_mutex hi::v1::detail::subsystem_mutex

inline

Mutex to be held when writing to system_status or accessing system_status_deinit_list.

The system status is also an atomic variable so that reads on system_status without holding the mutex is still possible.
