Rprintf(), on the other hand, prints straight to the R console; its first argument is the format string. Given a valid pointer to an uninitialised string instead of the format string, Rprintf prints stack garbage to the console, ignoring the following arguments. My guess is that the maintainers either intended to remove the msg argument altogether or needed to use snprintf() and pass the buffer size to fcn_message(). -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
