Frontend Function Calls

DVB frontend open() — Open a frontend device

DVB frontend close() — Close a frontend device

ioctl FE_GET_INFO — Query DVB frontend capabilities and returns information about the front-end. This call only requires read-only access to the device

ioctl FE_READ_STATUS — Returns status information about the front-end. This call only requires read-only access to the device

ioctl FE_SET_PROPERTY, FE_GET_PROPERTY — FE_SET_PROPERTY sets one or more frontend properties. FE_GET_PROPERTY returns one or more frontend properties.

ioctl FE_DISEQC_RESET_OVERLOAD — Restores the power to the antenna subsystem, if it was powered off due to power overload.

ioctl FE_DISEQC_SEND_MASTER_CMD — Sends a DiSEqC command

ioctl FE_DISEQC_RECV_SLAVE_REPLY — Receives reply from a DiSEqC 2.0 command

ioctl FE_DISEQC_SEND_BURST — Sends a 22KHz tone burst for 2x1 mini DiSEqC satellite selection.

ioctl FE_SET_TONE — Sets/resets the generation of the continuous 22kHz tone.

ioctl FE_SET_VOLTAGE — Allow setting the DC level sent to the antenna subsystem.

ioctl FE_ENABLE_HIGH_LNB_VOLTAGE — Select output DC level between normal LNBf voltages or higher LNBf voltages.

ioctl FE_SET_FRONTEND_TUNE_MODE — Allow setting tuner mode flags to the frontend.
