.. _query-dvb-frontend-info:

*****************************
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.

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
