Ben, just FYI I took take to add tests to node-ffi making sure passing in and returning structs by value (NodObjC depended on it). See:
- https://github.com/rbranson/node-ffi/blob/v1.2.5/test/ffi_tests.cc#L20-L32 - https://github.com/rbranson/node-ffi/blob/v1.2.5/test/foreign_function.js#L46-L61 I haven't yet found places where it doesn't work as expected, but perhaps more complex structs wouldn't work.
