0015 Synopsis
0016 ========
0017
0018 .. c:macro:: NET_ADD_IF
0019
0020 ``int ioctl(int fd, NET_ADD_IF, struct dvb_net_if *net_if)``
0021
0022 Arguments
0023 =========
0024
0025 ``fd``
0026 File descriptor returned by :c:func:`open()`.
0027
0028 ``net_if``
0029 pointer to struct :c:type:`dvb_net_if`
0030
0031 Description
0032 ===========
0033
0034 The NET_ADD_IF ioctl system call selects the Packet ID (PID) that
0035 contains a TCP/IP traffic, the type of encapsulation to be used (MPE or
0036 ULE) and the interface number for the new interface to be created. When
0037 the system call successfully returns, a new virtual network interface is
0038 created.
0039
0040 The struct :c:type:`dvb_net_if`::ifnum field will be
0041 filled with the number of the created interface.
0042
0043 Return Value
0044 ============
0045
0046 On success 0 is returned, and :c:type:`ca_slot_info` is filled.
0047
0048 On error -1 is returned, and the ``errno`` variable is set
0049 appropriately.
0050
0051 The generic error codes are described at the
0052 :ref:`Generic Error Codes <gen-errors>` chapter.
