int hal_start_threads();
int hal_stop_threads();BESKRIVELSE
The hal_start_threads() function starts all threads that have been created. This is the point at which realtime functions start being called.
The hal_stop_threads() function stops all threads that were previously started by hal_start_threads(). It should be called before any component that is part of a system exits. Called from a non-realtime process, it returns once every thread has finished the functions it was running, so their code can be unloaded. Called from realtime code, it does not wait.
RETURVERDI
Returns a HAL status code. hal_stop_threads() returns -ETIMEDOUT when a thread has not finished its functions within 1000 of its periods.
