25 File descriptor returned by a previous call to :c:func:`open() <dvb-ca-open>`.
28 Buffer with data to be written
31 Number of bytes at the buffer
36 This system call is only provided by the logical device
37 /dev/dvb/adapter0/dvr0, associated with the physical demux device that
38 provides the actual DVR functionality. It is used for replay of a
39 digitally recorded Transport Stream. Matching filters have to be defined
40 in the corresponding physical demux device, /dev/dvb/adapter0/demux0.
41 The amount of data to be transferred is implied by count.

57 - No data was written. This might happen if O_NONBLOCK was
58 specified and there is no more buffer space available (if
59 O_NONBLOCK is not specified the function will block until buffer
66 - This error code indicates that there are conflicting requests. The
67 corresponding demux device is setup to receive data from the
68 front- end. Make sure that these filters are stopped and that the
69 filters with input set to DMX_IN_DVR are started.
75 - fd is not a valid open file descriptor.
