| Querying frontend information |
| ***************************** |
| |
| Usually, the first thing to do when the frontend is opened is to check |
| the frontend capabilities. This is done using |
| :ref:`FE_GET_INFO`. This ioctl will enumerate the |
| Digital TV API version and other characteristics about the frontend, and can |
| be opened either in read only or read/write mode. |
