(

[virtual]

MythMediaError MythCDROMLinux::unlock

(

void

)

[virtual]

Reimplemented from MythMediaDevice.

Definition at line 608 of file mythcdrom-linux.cpp.

Referenced by checkMedia().

int MythCDROMLinux::driveStatus

(

void

)

[private]

Exhaustively determine the status.

If the CDROM is managed by the SCSI driver, then CDROM_DRIVE_STATUS as reported by ioctl will always return CDS_TRAY_OPEN if the tray is closed with no media. To determine the actual drive status we need to ask the drive directly by sending a SCSI packet to the drive.

bool MythCDROMLinux::hasWritableMedia

(

void

)

[private]

Is there blank or eraseable media in the drive?

Definition at line 183 of file mythcdrom-linux.cpp.

Referenced by checkMedia().

int MythCDROMLinux::SCSIstatus

(

void

)

[private]

Use a SCSI query packet to see if the drive is _really_ open.

Note that in recent kernels, whether you have an IDE/ATA/SATA or SCSI CDROM, the drive is managed by the SCSI driver and therefore needs this workaround. This code is based on the routine cdrom_get_media_event in cdrom.c of the linux kernel
