|
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.
