Do not use in new drivers. For V4L2 decoders 59this ioctl has been replaced by the ``V4L2_CID_MPEG_VIDEO_DEC_PTS`` 60control. 61 62This ioctl call asks the Video Device to return the current PTS 63timestamp. 64 65 66Return Value 67------------ 68 69On success 0 is returned, on error -1 and the ``errno`` variable is set 70appropriately. The generic error codes are described at the 71:ref:`Generic Error Codes <gen-errors>` chapter. 72
