- :name: NET_ADD_IF
- Arguments
- =========
- ``fd``

- 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
