Unmounting and 'eject' press

[Ikke]

Ok, I did the testings.

To unlock the tray: very simple

#include <stdio.h>
#include <fcntl.h>
#include <sys/ioctl.h>

#include <linux/cdrom.h>

int main()
{
        int fd;

        fd = open("/dev/hdc", O_RDONLY | O_NONBLOCK);
        if (fd == -1) {
                perror("open");
                return 1;
        }

        if(ioctl(fd, CDROM_LOCKDOOR, 0) < 0)
                 perror("cdrom tray lock");
        return 0;
}

gcc -o test test.c
mount /mnt/cdrom
./test
(press eject, cd ejects, I get error messages in syslog)

When running dbus-monitor --system while doing this test, Hal seems to send
a dbus message when the CD gets removed, so umounting should be possible :-)
Only need to implement some 'device is busy' test or something alike...

Maybe it's not the best solution, but well, I'll implement it temporarly in
ivman

Regards, Ikke
