zx_status_t AddDispatcher (fbl::RefPtr<Dispatcher> dispatcher)Returns ZX_OK if |dispatcher| was added successfully.
Returns ZX_ERR_BAD_STATE if the driver is currently shutting down.

void EnvReset ()static
Defined at line 1944 of file ../../src/devices/bin/driver_runtime/dispatcher.cc
void Reset ()Resets to 0 threads.
Must only be called when there are no outstanding dispatchers.
Must not be called from within a driver_runtime managed thread as that will result in a
deadlock.

If the thread pool does not exists, creates the thread pool and starts the initial thread.
Defined at line 1972 of file ../../src/devices/bin/driver_runtime/dispatcher.cc
void DestroyThreadPool (Dispatcher::ThreadPool * thread_pool)This will schedule the thread pool to be deleted on a thread on the default thread pool.
