It can be done. I think the issue had to do with getting the macros to work in R6RS libraries. I did redo the define-c-info macro into a R6RS library as a syntax-case macro.
Since that time I think(?) Larceny has added additional capability regarding its native explicit-renaming(?) macros inside R6RS libraries. So other approaches might work as well. My version of Larceny's FFI inside R6RS Libraries are here. http://github.com/GreyLensman/rl3/tree/75c05ae3c3e838dace63c18d4c5a95590ed304bb/rl3/ffi Examples of use are here: Sockets: http://github.com/GreyLensman/rl3/tree/75c05ae3c3e838dace63c18d4c5a95590ed304bb/rl3/io/net/sockets.sls EPoll: http://github.com/GreyLensman/rl3/tree/75c05ae3c3e838dace63c18d4c5a95590ed304bb/rl3/io/epoll.sls The last caveat is the code is Linux specific. If you are on Windows for examples you would have to add back a few cond-expands from Larceny's native version into my ported version. I'm open to any and all options regarding the RL3 code.
