Library of filter blocks used in gnuradio. Implements FIR, IIR and FFT filters, as well as Polyphase filterbank and PFB arbitrary resampler methods. Part of the main gnuradio build.

Library of blocks that implement UDP and TCP source and sink blocks supporting both IPv4 and IPv6. Part of the main gnuradio build.

Polymorphic Types are opaque data types that are designed as generic containers of data that can be safely passed around between blocks and threads in GNU Radio. Part of the main gnuradio build.

Top level component library. Defines core blocks. Handles settings for logging, performance counters, and control port. Part of the main gnuradio build.

Snapper is a tool for Linux filesystem snapshot management. Apart from the obvious creation and deletion of snapshots, it can compare snapshots and revert differences between snapshots. In simple terms, this allows root and non-root users to view older versions of files and revert changes.
