| Name |
| ==== |
| |
| NET_ADD_IF - Creates a new network interface for a given Packet ID. |
| |
| |
| Synopsis |
| ======== |
| |
| .. c:function:: int ioctl( int fd, NET_ADD_IF, struct dvb_net_if *net_if ) |
| :name: NET_ADD_IF |
| |
| |
| Arguments |
| ========= |
| |
| ``fd`` |
| File descriptor returned by :ref:`open() <frontend_f_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. |
