Comment(by hellais):
I am not sure how to rephrase this in terms of syscalls, but I can tell
you how I ran into this problem.
Basically when writing the HTTP transport I need to slap some header on
top of packets I send that are managed inside of an evbuffer. I add
headers both at the beginning of the packet and at the end of it. The
problem is that when a packet is bigger than 4096 bytes it gets fragmented
and I should be able to slap the begin header on the first fragment and
the end header on the last one.
If I don't do this there are problems when stripping the headers off of
the packets and reading the content.
Is there a way to understand if the current chunk is the last one?
