Hi, I'm trying to use these to serialize messages to my own
stream.
I have a couple of questions:
1. If I use message.SerializeToCodedStream() do I still need to
write
the size of the message to the stream on my own first?
Yes.
2. My new code looks like this:
MyStream myStream; // this implements CopyingOutputStream
CopyingOutputStreamAdaptor protoBufStream(&myStream);
CodedOutputStream codedOutputStream(&protoBufStream);
Then I write messages like this:
message.SerializeToCodedStream(&codedOutputStream);
When the CodedOutputStream's destructor gets called, my program
aborts
hard.. Looks like there is still 5192 bytes in its buffer, and I
think
I need to call Flush() on it, but there is no flush?
What is the error message? Stack trace?
thx
