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 ` chapter.
