I'm trying to use the GNU Radio library (written in C++) from scheme.
While I can't really modify the library itself, I can wrap functions I

In one of the messages in the earlier thread, I found a link to
https://isocpp.org/wiki/faq/mixing-c-and-cpp

That page gives me some idea of how I can write C wrappers for my C++
library.
