The current code doesn't work. If the supplied output buffer is too small, the caller does not receive the required size in lpBytesReturned as intended. Relevant blog post: http://bit.ly/1NxJik3 I am simply switching to a reasonably sized fixed buffer on the calling side, exactly what SerialPort::SerialPort() does. The IOCTL implementation is tweaked to make it clear that the buffer size is not communicated back on failure.
