Hi,fd = open("/dev/sr0", O_RDWR);root@transponder:/home/garydale# ./open_sr0 open: fd= -1 , errno= 30 open: Read-only file systemThis 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 ?
root@transponder:/home/garydale# ./open_sr0 open: fd= 3 , errno= 0 write: ret= 2048 , errno= 0 No one in Debian user has been able to shed any light on the problem. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
