c++ - capnp - how to write plain serialized message to a file

Question

I have build the example of the AddressBook from Example Usage. It worked as expected I serialized it in the packed format writePackedMessageToFd(fd, message), but when I tried to serialize it in the 'plain' format writeMessageToFd(fd, message)

it kept producing empty file... I feel that I'm missing something...

这只是一个混乱，该文件只写了我在 Eclipse 内部阅读器中看不到它。
