This is surprising, because xorriso uses
open(..., O_RDWR | O_NDELAY);
when it acquires a drive.
(I would have expected to see the error with write(), which xorriso
does not use.)
Whay happens if you change the test program
- fd = open("/dev/sr0", O_RDWR);
+ fd = open("/dev/sr0", O_RDWR | O_NDELAY);
compile it, and run again as superuser ?
Whatever, a BD-RE device with rw-permission on its device file should
not throw this error.
We need kernel expertise to find out what happens here.
Is anybody at debian-user able to give advise or propose experiments
which shed light on the problem ?
Have a nice day :)
Thomas
