void MediaMonitorUnix::CheckDeviceNotifications ( void ) [protected, virtual]

bool MediaMonitorUnix::CheckMountable ( void ) [protected]

Search /sys/block for valid removable media devices.

This function creates MediaDevice instances for valid removable media devices found under the /sys/block filesystem in Linux. CD and DVD devices are created as MythCDROM instances. MythHDD instances will be created for each partition on removable hard disk devices, if they exist. Otherwise a single MythHDD instance will be created for the entire disc.

NOTE: Floppy disks are ignored.

bool MediaMonitorUnix::FindPartitions	(	const QString &	dev,
		bool	checkPartitions
	)			`[protected]`

Creates MythMedia instances for sysfs removable media devices.

Block devices are represented as directories in sysfs with directories for each partition underneath the parent device directory.

This function recursively calls itself to find all partitions on a block device and creates a MythHDD instance for each partition found. If no partitions are found and the device is a CD or DVD device a MythCDROM instance is created. Otherwise a MythHDD instance is created for the entire block device.

Parameters:
