That's crucial, and README does warn you about it.

Therefore I would like to know if there exits any examples that explain
how to do this and if it is possible to do only by calls to the r.dll.
The main reason that I play around with rtest.c is that I was trying
to build something similarly with Delphi (where I only have access to
the R.dll ) and ran into the same problems.

As I said before, use the DCOM interface unless you know what you are doing.
There is an example of an error handler, of course, the R code
itself. But beyond that I don't think you can reasonably ask for
help.

Please teach your mailer to wrap lines.
