Hi Bert, No, it does not (AFAIK, please correct me). Basicaly, you can call some (NOT all) functions exported by kernel. See man ksyms how to get a list. You can call functions provided by other modules you have insmod-ed. And finally you can link (ld -r) your module with some libraries. If your question is about calling standard C functions, the answer is no. I've put together a restricted set of standard C functions (mostly string & format) that I link with my RT modules.
