20``int ioctl(int fd, NET_ADD_IF, struct dvb_net_if *net_if)``
21
22Arguments
23=========
24
25``fd``
26    File descriptor returned by :c:func:`open()`.
27
28``net_if``
29    pointer to struct :c:type:`dvb_net_if`

31Description
32===========
33
34The NET_ADD_IF ioctl system call selects the Packet ID (PID) that
35contains a TCP/IP traffic, the type of encapsulation to be used (MPE or
36ULE) and the interface number for the new interface to be created. When
37the system call successfully returns, a new virtual network interface is
38created.
39
40The struct :c:type:`dvb_net_if`::ifnum field will be
41filled with the number of the created interface.
42
43Return Value
44============
45
46On success 0 is returned, and :c:type:`ca_slot_info` is filled.
47
48On error -1 is returned, and the ``errno`` variable is set
49appropriately.

51The generic error codes are described at the
52:ref:`Generic Error Codes <gen-errors>` chapter.
