# PWN::FFI::RTLSdr

Thin librtlsdr binding (no -dev headers required — symbols resolved from the installed shared object). Control-plane + blocking `read_sync` so PWN::SDR::Decoder::* / Extrospection probe_rf can pull raw u8 I/Q without shelling out to `rtl_sdr`. If librtlsdr is missing `.available?` is false and callers fall back.

## When to use

Call `PWN::FFI::RTLSdr` from `pwn_eval` when the task needs this module.
Do not reimplement it in shell.

## Methodologies

Generated from `pwn/ffi/rtl_sdr.rb`. Prefer the public class methods below.
Class methods take `(opts = {})` and read `opts`.
