Re: Making C++ OOT module and wish to set up a parameter with different choices!

I do not claim to cover all aspect of OOT blocks but I tried to document the basics of
passing parameters and public/private variables at
http://jmfriedt.free.fr/gr_oscilloscope_eng.pdf

Unfortunately this document only covers GNU Radio 3.7: while the French version was extended to
GNU Radio 3.8, the English version was not extended accordingly but I'd be happy to do so if there
is any interest.
