This would be a nice feature to have, since resizable arrays are so useful. > Ideally, on platforms like Linux, we'd use mmap() instead of malloc, > and then extending a rvarray would not require copying anything > (just change the address of the existing pages). However the implementation > is a bit hairy and platform dependent. I've never done much with mmap, but I do know that llvm has cross platform bindings to the various mmap implementations. Since they're BSD too, it might be worthwhile looking at how they do it, and possibly using their code too instead of maintaining our own platform independent bindings. ------------------------------------------------------------------------------ _______________________________________________ Felix-language mailing list Felix-language@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/felix-language
