| Name |
| ==== |
| |
| NET_ADD_IF - Creates a new network interface for a given Packet ID. |
| |
| |
| Synopsis |
| ======== |
| |
| .. cpp:function:: int ioctl( int fd, int request, struct dvb_net_if *net_if ) |
| |
| |
| Arguments |
| ========= |
| |
| ``fd`` |
| File descriptor returned by :ref:`open() <frontend_f_open>`. |
| |
| ``request`` |
| FE_SET_TONE |
| |
| ``net_if`` |
| pointer to struct :ref:`dvb_net_if <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 :ref:`dvb_net_if <dvb-net-if>`::ifnum field will be |
| filled with the number of the created interface. |

| |
| - pid |
| |
| - Packet ID (PID) of the MPEG-TS that contains data |
| |
| - .. row 3 |
| |
| - ifnum |
| |
| - number of the DVB interface. |
| |
| - .. row 4 |
| |
| - feedtype |
| |
| - Encapsulation type of the feed. It can be: |
| ``DVB_NET_FEEDTYPE_MPE`` for MPE encoding or |
| ``DVB_NET_FEEDTYPE_ULE`` for ULE encoding. |
| |
| |
| Return Value |
| ============ |
| |
| On success 0 is returned, on error -1 and the ``errno`` variable is set |
| appropriately. The generic error codes are described at the |
| :ref:`Generic Error Codes <gen-errors>` chapter. |
