Check if the daemon needs to be notified by the event.
On mount event: If the device mount point contains the DLT configuration file, the function will then send a message to the daemon. On Unmounting event: Check if the device was on the list, remove it and send the message to the daemon.
The kind of event happening The device partition to be checked
- Returns
- 0 on success, -1 if an error occured.

Check all partitions on the system to find configuration file.
The function looks for block devices that are of "partition" type. Then, it gets the node, and call check_mountpoint_from_partition with it.
The udev device used to find all the nodes
- Returns
- 0 on success, -1 otherwise.

Clean-up the udev data.
That will destroy all the private data.
- Returns

Get mount point of a device node.
This function search for the mount point in /proc/mounts based on the device node.
- Parameters
-
dev_node Device node as string
- Returns
- mount path or NULL on error

| int dlt_logstorage_udev_init | ( | void | ) |
Initialize the private data.
That function will create the udev device and monitor.
- Returns

Handles the udev events.
On event, it finds the corresponding action, and calls check_mountpoint_from_partition with the corresponding event.
- Returns
- 0 on success, -1 on error.
