When this ioctl is called the driver will output the -current device status to the kernel log. This is particular useful when -dealing with problems like no sound, no video and incorrectly tuned -channels. Also many modern devices autodetect video and audio standards -and this ioctl will report what the device thinks what the standard is. -Mismatches may give an indication where the problem is. - -This ioctl is optional and not all drivers support it. It was introduced -in Linux 2.6.15. - - -Return Value -============ - -On success 0 is returned, on error -1 and the ``errno`` variable is set -appropriately. The generic error codes are described at the -:ref:`Generic Error Codes <gen-errors>` chapter. |
