Is DataChannelObserver::OnMessage() chunk size maintained?

[James Inkster]

(I'm using native C++...)

I have a datachannel to which I send, say, 1024 bytes of binary data via Send()

I understand that the data is buffered internally on the sending end, but when OnMessage() is called will I get the entire/exact chunk, or could it appear in different sizes?

I need to know whether or not my receiving code needs to implement a parser...

ie., 

Send (1024 bytes) ---> OnMessage (1024 bytes)

OR

Send (1024 bytes) --> OnMessage (512 bytes), OnMessage (512 bytes)

Likewise,

Send (1024 bytes), Send (512 bytes) --> OnMessage (1536 bytes) 

OR

Send (1024 bytes), Send (512 bytes) --> OnMessage (1024), OnMessage (512)

Thanks!

The data channel should preserve message boundaries.
