The #ifdef _WIN32 below this line makes me assume that this file is also compiled on Windows, which means that this include here (and the actual function that was added) should probably be in #ifndef _WIN32 guards?
When using ffi.toBuffer, memory protection on any memory pages exposed must be observed by the caller, otherwise crashes will occur. Now documented, and tested.
