   13  * @page c_posCtrl Positioning Control API
   14  *
   15  * @ref le_posCtrl_interface.h "API Reference"
   16  *
   17  * <HR>
   18  *
   19  * This API is used to enable and disable the positioning service.
   20  *
   21  * All other positioning functionality is provided by the @ref c_pos.
   22  *
   23  * @section le_posCtrl_binding IPC interfaces binding
   24  *
   25  * All the functions of this API are provided by the @b positioningService application service.
   26  *
   27  * Here's a code sample binding to Positioning services:
   28  * @verbatim
   29    bindings:
   30    {
   31       clientExe.clientComponent.le_posCtrl -> positioningService.le_posCtrl
   32    }
   33    @endverbatim
   34  *
   35  * @section le_posCtrl_ctrl Positioning control
   36  *
   37  * To request that the positioning service be activated, call le_posCtrl_Request().
   38  *
   39  * To release the positioning service when finished with it, call le_posCtrl_Release().
   40  *
   41  * If the positioning service is already active when le_posCtrl_Request() is called, it will remain
   42  * active.  This happens if another application has already requested that the positioning service
   43  * be activated and not yet released the positioning service.
   44  *
   45  * The positioning service (and associated devices) will not necessarily be switched off when
   46  * an application calls le_posCtrl_Release(). The positioning service will be switched off only
   47  * after all applications that have requested that the positioning service be active have also
   48  * released the positioning service.
   49  *
   50  * @note    Control of the positioning service is done through a separate API than the retrieval
   51  *          of positioning information to allow access to positioning information by less-trusted
   52  *          applications, while only allowing control of the positioning system by more-trusted
   53  *          applications.
