Dev list don't receive my last mail !!!?

never mind, i made other attempts.

When i put a cd in drive and watch the log i can see :
Failed to open device, CDROM try will remain locked.

Then i try to open device when cdrom is mounted, and open function 
return always -1.
If i try :
system("mount /mnt/cdrom")
int handle = open("/dev/cdrom",O_RDONLY | O_NONBLOCK | O_EXCL)
int stat = ioctl(handle,CDROM_LOCKDOOR,0);

it's failed because handle = -1

If i try :
int handle = open("/dev/cdrom",O_RDONLY | O_NONBLOCK | O_EXCL)
system("mount /mnt/cdrom")
int stat = ioctl(handle,CDROM_LOCKDOOR,0);
it's work.


I have add cout message in opendevice and close device.here is the log :

Found a handler

the problem is that you close device before mount it then handle device = -1

then is watch performMountCmd function in mythmediadevice
and i can see that you made this :
    if (isDeviceOpen())
        closeDevice();
before mount the device

Can you explain why ?

I remove the both lines then i can eject my cdrom but mediamonitoring never umount this device and never send other event for this driver after this.

send information by an event object will be a solution except if we are 
more than one cdrom device.
if you put in the first one, mediahanlder can receive information about 
this drive
if you put in the second one, mediahanlder can receive information only 
about the second drive, except the both have cdrom inserted then .... 
any idea  about that ?
Parse fstab can be the solution, but it will be better if only 
mediamonitor do that.
