NET_ADD_IF - Creates a new network interface for a given Packet ID.
|
|
|
|
Synopsis
|
|
========
|
|
|
|
.. c:macro:: NET_ADD_IF
|
|
|
|
``int ioctl(int fd, NET_ADD_IF, struct dvb_net_if *net_if)``
|
|
|
|
Arguments
|
|
=========
|
|
|
|
``fd``
|
|
File descriptor returned by :c:func:`open()`.
|
|
|
|
``net_if``
|
|
pointer to struct :c:type:`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 :c:type:`dvb_net_if`::ifnum field will be
|
|
filled with the number of the created interface.
|
|
|
|
Return Value
|
|
============
|
|
|
|
On success 0 is returned, and :c:type:`ca_slot_info` is filled.
|
|
|
|
On error -1 is returned, and the ``errno`` variable is set
|
|
appropriately.
|
|
|
|
The generic error codes are described at the
|
|
:ref:`Generic Error Codes <gen-errors>` chapter.
