Overview

The /pps/qnx/mount/ directory contains objects that hold information for all devices mounted in the system. Object names are of the form:

rawdevice[.partition#]

For example, for a USB stick (/dev/umass0) with a DOS partition, the PPS objects would be named:

/pps/qnx/mount/umass0

/pps/qnx/mount/umass0.0

Here's a sample USB object: 
[n]@umass0.0
PPS_DRIVER_ID::/pps/qnx/driver/2052107
PPS_RAWMOUNT_ID::/pps/qnx/mount/umass0
blocks_size::512
blocks_total::7830408
fs_type::dos (fat32)
id::6485a02e-4cd0-4ed6-80a1-a0bce5acde3e
label::KINGSTON
mnt_status::0 (No error)
mount::/fs/usb0
name::KINGSTON
partition::/dev/umass0t11
partition_order::0
plugin_name::generic
raw::/dev/umass0
read_only::0

partition Device partition (e.g., /dev/umass0t11).
partition_count Number of partitions on this raw device.
partition_order Order in the partition table.
plugin_name Name of the plugin used for this device.
PPS_DRIVER_ID Name of the PPS object that contains information about the device driver.
PPS_RAWMOUNT_ID Name of the PPS object that contains information about the raw device.

Note: The Juke Box app happens to create the following object under the /pps/qnx/mount/ directory: 
@mme
device_type::hdd
fs_type::qnx
id::mme
mount::/accounts/1000/shared/
name::Juke Box

Note that the device_type attribute and hdd value here are specific to the QNX CAR platform.
