| .. c:function:: int ioctl(fd, int request = VIDEO_STOP, boolean mode) |
| - File descriptor returned by a previous call to open(). |
| - Equals VIDEO_STOP for this command. |
| - Indicates how the screen shall be handled. |
| - TRUE: Blank screen when stop. |
| - FALSE: Show last decoded frame. |
| This ioctl is for DVB devices only. To control a V4L2 decoder use the |
| V4L2 :ref:`VIDIOC_DECODER_CMD` instead. |
| This ioctl call asks the Video Device to stop playing the current |
| stream. Depending on the input parameter, the screen can be blanked out |
| or displaying the last decoded frame. |
| 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. |
