The QNX Web Browser supports the ppsService object, which provides HTML5 applications with JavaScript access to the QNX Persistent Publish/Subscribe (PPS) service. By using the ppsService methods, an application can read or write to PPS objects used by services running on the QNX Neutrino RTOS or QNX CAR platform.
The ppsService object is created as a global object on the page, unless you specify the --qnx-disable-pps-service-bindings command-line option.
