Assuming you are running example 2. Some time ago the interface was changed to provide a more C-like (and less C++ like) interface, so dataOut is defined as given below, // dynamic label data, embedded in the audio stream, is sent as string typedef void (dataOut_t)(const char , void *);
it asks for a char * as parameter rather than a std::string.
/ / The function is called from within the library with // a string, the so-called dynamic label static void dataOut_Handler (const char dynamicLabel, void ctx) { (void)ctx; std::cerr << std::string (dynamicLabel) << "\r"; }

I am trying to work from a known basis to extract 'Now Playing information from BBC Radio 3 DAB and having problems. (I am working from an example as my coding skills are not great, nor my understanding of DAB. I am very grateful for the code and the hard work behind it - thank you!)
My modification looks like this:
// The function is called from within the library with // a string, the so-called dynamic label static void dataOut_Handler (std::string dynamicLabel, void *ctx) { (void)ctx; fprintf (stderr, "data out called\n"); fprintf (stderr, "%s\n", dynamicLabel. c_str ()); } // The only output produced is typically of this form:
data out called NlaLuur)
Observation of a DAB tuner shows that the program data being streamed bears no resemblance whatsoever to this, and I am at a loss to understand what is happening, unless I am perhaps mis-handling a pointer?
All suggestions would be welcome!
Many thanks,
Ben
