*Question:* what is the best way to access a DOTSXP from R's C API in a function call.
Over at extendr (1) we'd like to be able to utilize `...` from the body of a Rust function—with initial motivation being to support S3 generics like print(x, ...). I don't see any recommendations / or mention of accessing DOTSXP in WRE. The closest I can find is from R internals (2) repo which says "Easiest to get to with findVar(R_DotsSymbol, env) or similar." >From R's C API would this mean we would want to use something like: findVar(R_DotsSymbol, R_GetCurrentEnv()) to get the dots pairlist from the function's environment? 1) https://extendr.rs 2) https://github.com/hadley/r-internals/blob/16c1d73b635ccecec8b1f396a8935a8dd96126e4/pairlists.md [[alternative HTML version deleted]] ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
