Dear all, I'd like to be able to read from an arbitrary R connection (in the sense of ?connections), which would be passed to an R function by the user and then down into some C code via .Call.
The R API, in file R_ext/Connections.h, specifies a function, R_ReadConnection, which takes a pointer to an Rconn struct as its first argument, and does what I want. The struct itself is also defined in that header, but I see no way of retrieving a struct of that type, aside from getConnection (the C function), which is not part of the API. As far as I can tell, the external pointer associated with the connection also does not point to the struct directly. So, could anyone please tell me whether there is a supported way to convert a suitable SEXP to a pointer to the associated Rconn struct? Thanks in advance. Jon (This question was also posted yesterday to StackOverflow <http://stackoverflow.com/questions/35483523/r-reading-from-an-existing-connection-in-compiled-code>, but no definitive answer has been posted.) ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
