gr::blocks::tagged_stream_to_pdu Class Reference

Turns received stream data and tags into PDUs and sends them through a message port.The sent message is a PMT-pair (created by pmt::cons()). The first element is a dictionary containing all the tags. The second is a vector containing the actual data. More...

Detailed Description

Turns received stream data and tags into PDUs and sends them through a message port.

The sent message is a PMT-pair (created by pmt::cons()). The first element is a dictionary containing all the tags. The second is a vector containing the actual data.
