After opening a TCP socket and doing a large number of successful reads and
writes (I always check the return value of write), write suddenly reports
that it has only written a partial buffer.
I am wondering if this is a flow-control problem in that the writer is
getting too far ahead of the reader. I would have expected the write to
block just like a pipe. If this is the problem, is there some option I
should set or am I supposed to handle flow-control myself on top of TCP?
I'm grasping at straws, however and don't really think that's the problem.
So anyway, what are the possible reasons for write returning a size that is
positive but less than the requested size. (Oh, and yes, I'm sure that
the process at the other end is still alive and didn't close the socket.)
