gnuradio.blocks.message_debug() → message_debug_sptr

Debug block for the message passing system.

The message debug block is used to capture and print or store messages as they are received. Any block that generates a message may connect that message port to one or more of the three message input ports of this debug block. The message ports are:

Constructor Specific Documentation:

Build the message debug block. It takes no parameters and has three message ports: print, store, and print_pdu.
