I don't think R supports user-defined connections, but probably
writing readBin and writeBin equivalents specific to your library
wouldn't be any harder than creating a connection. For those, you
will probably want to work with an "external pointer" (see Writing R
Extensions). Rcpp probably has support for these if you're working in
C++.
Thank you, yes I was following
https://stackoverflow.com/questions/59384221/proper-way-to-return-a-pointer-to-a-new-object-from-an-rcpp-function
which uses XPtr.
I'll forget about making a connection, if it is not supported.
I had this idea that I would be able to use the same code for writing to a file
as to an audio device, but I can create my own class for that.
