This appeared in the R 3.3.0 NEWS:

Found non-API calls to R: ?R_GetConnection?,
?R_new_custom_connection?
Compiled code should not call non-API entry points in R.
See 'Writing portable packages' in the 'Writing R Extensions' manual.
Connections in general seem more useful than ad-hoc functions, though perhaps for Frederick's use cas...

PATCH: Asserting that 'connection' used has not changed + R_GetConnection2()
...ted connection. The 'id' field is available via
attribute 'conn_id' part of a 'connection' object.
PATCH:
See attached 'connection.patch' file (or
https://github.com/HenrikBengtsson/Wishlist-for-R/issues/81#issuecomment-434210222).
The patch introduces a new SEXP R_GetConnection2(SEXP sConn) function,
which looks up a connection by its index *and* the 'id' field. This
function is backward compatible with R_GetConnection(), which looks up
a connection by its index (only). In addition, R_GetConnection2() also
accepts 'sConn' of type integer, which the look...

Discussion starter for package level Connection API
...ght balance between opening up the
internals to package writers and not allowing them to do bad things. My
first attempt at cracking this nut is to just memcpy() the Rconnection
and not allow access to the private stuff:
/* Alternative to allowing C code access to connection API. */
Rconnection R_GetConnection(Rconnection ucon, int idx){
Rconnection rcon;
/* Valid connection? */
if ((rcon = getConnection(idx)) == NULL)
return NULL;
memcpy(ucon,rcon,sizeof(struct Rconn));
/* Don't reveal private data */
ucon->private = NULL;
return ucon;
}
This wo...

defining r audio connections
The public connection API is defined in
https://github.com/wch/r-source/blob/trunk/src/include/R_ext/Connections.h
I'm not sure of a good pedagogic example; people who want to write their own connections usually want to do so for complicated reasons!
This is my own abandoned attempt
