Hello cafe, I've been poking around and I haven't seen this addressed anywhere except obliquely in the end of section 8.5.1 of the report, where it says that variable argument C functions aren't supported:
http://www.haskell.org/onlinereport/haskell2010/haskellch8.html The scenario is pretty simple. I generate C code at runtime. I compile it to a .so. I know how many arguments it expects (but only at runtime), and I get a FunPtr back from 'dlsym'. How do I call it? I was hoping there would be some "Raw" lower level FFI layer that I could use to invoke a C function without automagic marshaling and all the other goodness provided by the normal "foreign import" mechanism. Failing that, will I just have to generate complex wrappers on the C side which I call N times to load up N arguments into some stateful container before finally launching the function? Thanks, -Ryan
