search for: attribute_hidden

...ravis build: https://travis-ci.org/fstpackage/lazyvec/jobs/539442806 The reason of build failure is that many ALTREP methods generate 'undefined symbol' errors upon building the package (on Linux). I've checked the R source code and the undefined symbols seems to be related to the 'attribute_hidden' before the function definition. For example, the method 'ALTVEC_EXTRACT_SUBSET' is defined as: SEXP attribute_hidden ALTVEC_EXTRACT_SUBSET(SEXP x, SEXP indx, SEXP call) My question is why these differences between Windows / OSX and Linux exist and if they are intentional? Do I need s...

thanks for clearing that up, so these methods are actually not meant to be exported on Windows and OSX? Some of the ALTREP methods that now use 'attribute_hidden' would be very useful to packages that aim to be ALTREP aware, should the currently (exported) API be considered final? thanks for your time & best, Mark On Tue, Jun 4, 2019 at 6:52 PM Tierney, Luke <luke-tierney at uiowa.edu> wrote: > On Tue, 4 Jun 2019, Mark Klik wrote: >...

Currently the function Rstd_Busy() does nothing (src/unix/sys-std.c): void attribute_hidden Rstd_Busy(int which) { } The function is called through a pointer and R interfaces can change this pointer and, thus, use a different function. I don't plan to create a whole new interface to R, but I maintain a package whose aim is to provide a new feature to R when it's running i...

And the do_docall function is defined in <src>/main/coerce.c line 2217 and declared as SEXP attribute_hidden do_docall(SEXP call, SEXP op, SEXP args, SEXP rho) in Internal.h. The problem is that I do not guess the exact meaning of theses arguments, and the header file Internal.h is not found when included in my C file. As this header is not listed in R-exts.pdf section 6.17, I think I cannot use the do_...

Hi, Short version of my question: Rf_applyClosure was marked attribute_hidden in Oct 2023, and I am curious why and if there is an alternative interface to it planned. Long version: I have been toying with building a package that makes it easier to do non-standard evaluation directly using promises, rather than wrapping these in a custom type (like e.g. rlang does). The ad...

I'm trying to efficiently allow conversion of R objects to PostgreSQL bytea (raw binary) datatype within PL/R for persistent storage in Postgres tables. I have found R_serialize() which looks like what I need, -- e.g. R_serialize(object, NULL, FALSE, NULL) -- except that it is marked attribute_hidden. Is there some other externally available interface that I can use? Thanks, Joe

Hi all. I began examining the R source code in the last few days, for a better understanding of its structure. I read the manuals and digged deeply (maybe not enough?) into the source code, but I couldn't totally understand how .Primitive() works. Its effects, if I understand well, are quite clear to me (calling the C compiled counterpart of a "primitive" function), but where is its
