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.
