      - Sensor Library Overview
        The Sensor library provides applications with a consistent interface to simultaneously access up to 64 sensors connected to the hardware platform.
      - Opening and closing a connection to a sensor unit
        Applications use a handle provided through the Sensor API to access each of the logical sensor units that are configured in the sensor configuration file.
      - Starting and stopping a sensor unit
      - Opening and closing a connection to an interim data unit
        Applications use a handle provided through the Sensor API to access each of the interim data units that are configured in the interim data configuration file.
      - Starting an interim data unit
      - Accessing sensor data and status
        Applications can access the sensor's data and status by binding callback functions or events that are of the structure sigevent to sensor events that are of particular interest.
      - Publishing interim data
        Publishers are applications that generate interim data information for other applications.
      - Subscribing to interim data
        Subscribers are applications that use interim data that publishers generate.
      - Recording data from a sensor
        Applications can record the data that's streaming from a sensor to a file.
      - Querying sensor information
      - Using external clocks
        Sensor timestamps can be based on a reference time provided by an external clock library.
      - Using external sensor drivers
        Sensors that aren't already supported by the Sensor Framework for QNX SDP can be provided by an external sensor driver library.
