+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.
