Yes. You can't produce a single ctype that represents a vararg function, but you can create a wrapper that will produce (and call) a fixed-arity ffi wrapper, based on the number of actual parameters you pass it. See this example (using C's printf) by Eli Barzilay: [http://svn.plt-scheme.org/plt/trunk/collects/ffi/c-printf.ss]. This came out of a mailing list discussion from 2005: [http://lists.racket-lang.org/users/archive/2005-October/009848.html]. (The example code may or may not run as-is, since it's from an older version of the language.)
