Subject zoo_get - how to get full item?
Date Tue, 10 Jun 2014 03:55:53 GMT
hello,

I am sorry for the very n00b question. But I read whole documentation, did
search for the archives but still do not understand how to get full data
from ZK using C binding zoo_get.

I expect that
*buffer_len* is the size of the buffer
<http://zookeeper.sourcearchive.com/documentation/3.2.2plus-pdfsg3-2/structbuffer.html>
pointed to by the buffer
<http://zookeeper.sourcearchive.com/documentation/3.2.2plus-pdfsg3-2/structbuffer.html>
parameter. It'll be set to the actual data length upon return. If the data
is NULL, length is -1.

will return me actual data size but it did not. So if I send buffer with
size 1 for the data size 3 it returns me 1 in buffer_len :(  (i expect 3 to
allocate new buffer of size 3)

It seem I miss something simple but cannot figure out what.

Thank you,
Denis
