兰天, writefunction should return exactly the number of bytes that
libcurl gives it.
Please add logging to your writefunction and check if perhaps it fails
with an error.

For example, if your writefunction looks like `return write(somefd,
data, len)`, then it stands to reason that underlying `write` returned
-1 to indicate an error.

Another (very remote) possibility is that you use an integer of wrong
size somewhere. I'd hazard a guess that 2**14 just happens to be
buffer size.
>>> bin(16384)
'0b100000000000000'

When you've verified your write function, please test against newest
libcurl built from source.
