Hi,
IOCTL fails for retrieval/setting of tty/console mode. Below is the code
snippet:
fd = open("/dev/tty",O_NOCTTY);
if(fd == -1)
{
printf("Could not open /dev/tty.\n");
}
vt_mode.mode = VT_PROCESS;
vt_mode.waitv = 0;
vt_mode.relsig = SIGUSR1;
vt_mode.acqsig = SIGUSR2;
if (-1 == ioctl(fd,VT_GETMODE, &vt_omode))
{
printf("Could not get VT mode");
}
the above code provides "Could not get VT mode" message. Similar message
comes for /dev/console too.
Same code works perfectly on Linux Desktop. so I would like to know whether
VT_GETMODE is supported in the MVL for DM6446.
