Thank you. I print out 'errno' after I call 'ioctl', and from here:http://docsrv.sco.com/cgi-bin/man/man?ioctl+2, EPERM is not one of the errno set by ioctl. int result = ioctl(fd, KDSETMODE, (void*) KD_TEXT); if(result < 0) { LOGE("exit gr_init 1 %d\n", errno); close(fd); return -1; } >> >> Can you please tell me what am I doing wrong? >> >> Thank you. >> >> > > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
