There are the following main differences regarding tags in GNU Radio 4.0, compared to GNU Radio 3.10: * A GNU Radio 4.0 tag has a relative <code>index</code> and a <code>map</code> which is a <code>gr::property_map = std::map<std::string, pmtv::pmt></code>. This means that a single tag can hold multiple pieces of data, each with a different key in the <code>std::map</code>. In comparison, a GNU Radio 4.0 ta...")

This block has an input and an output, and only lets the first <code>num_items</code> input items make it through to the output. The code for the block is shown below, without the required <code>#include</code>s. Typically the code for the block will be placed in a <code>.hpp</code> file with include guards and at least <code><gnuradio-4.0/Block.hpp></code> a...")
