----------------------------------------

             Summary: Compile error due to LOGSTREAM being null when passed to fprintf
                 Key: ZOOKEEPER-3569
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3569
             Project: ZooKeeper
          Issue Type: Bug
          Components: c client
            Reporter: Ronald Fenner


I'm trying to compile the source and getting this error

Looking through the code in include/zookeeper_log.h at line 30 LOGSTREAM is defined as NULL.
This cause the above error.

In the 4.4.x branch it was getLogStream().

I believe this for the 3.5 branch should be zoo_get_log_stream()
