  \brief vos_get_binary_blob() - get binary data from platform
  This API allows components to get binary data from the platform independent
  of where the data is stored on the device.
  <ul>
    <li> Firmware
    <li> Configuration Data
  \param binaryId - identifies the binary data to return to the caller.
         raw binary data and update the *pBufferSize with the exact
         size of the data that has been retreived.
         the size of the binary data in *pBufferSize.
         size of the data buffer available at pBuffer.  Upon success, this
         retreived and written to the buffer at pBuffer.
         Input value of 0 is valid and will cause the API to return
         the size of the binary data in *pBufferSize.
          retreived and written to the buffer.
          refer to a valid VOS Binary ID.
          variable that the API can write to.
          *pBufferSize is not big enough to contain the binary.
