.. _NET_ADD_IF:
****************
ioctl NET_ADD_IF
****************
Name
====
NET_ADD_IF - Creates a new network interface for a given Packet ID.
Synopsis
========
.. c:function:: int ioctl( int fd, int request, struct dvb_net_if *net_if )
Arguments
=========
``fd``
File descriptor returned by :ref:`open() <frontend_f_open>`.
``request``
FE_SET_TONE
``net_if``
pointer to struct :ref:`dvb_net_if <dvb-net-if>`
Description
===========
The NET_ADD_IF ioctl system call selects the Packet ID (PID) that
contains a TCP/IP traffic, the type of encapsulation to be used (MPE or
ULE) and the interface number for the new interface to be created. When
the system call successfully returns, a new virtual network interface is
created.
The struct :ref:`dvb_net_if <dvb-net-if>`::ifnum field will be
filled with the number of the created interface.
.. _dvb-net-if-t:
struct dvb_net_if description
=============================
.. _dvb-net-if:
.. flat-table:: struct dvb_net_if
:header-rows: 1
:stub-columns: 0
- .. row 1
- ID
- Description
- .. row 2
- pid
- Packet ID (PID) of the MPEG-TS that contains data
- .. row 3
- ifnum
- number of the DVB interface.
- .. row 4
- feedtype
- Encapsulation type of the feed. It can be:
``DVB_NET_FEEDTYPE_MPE`` for MPE encoding or
``DVB_NET_FEEDTYPE_ULE`` for ULE encoding.
Return Value
============
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.
