The dacs_runtime_init and dacs_runtime_exit services initialize and close down access to the DaCS library.
Call dacs_runtime_init() before you use any other DaCS services, and do not use any DaCS services after you have called dacs_runtime_exit().
Calling dacs_runtime_exit() on an AE causes the communications between the AE and HE to be stopped. Calling dacs_runtime_init() after dacs_runtime_exit() will fail because once communications are stopped they can only be initiated by the HE calling dacs_de_start() to start a new process.
