Description. 
            This function, added in MySQL 5.1.16, is used to obtain log
            category and level information. It replaces the older
            ndb_mgm_get_loglevel_clusterlog()
            function, which performed the same purpose, but was not
            thread-safe. (See later in this section for a brief
            description of the deprecated version of the function.)
          
Signature.
int ndb_mgm_get_clusterlog_loglevel
    (
      NdbMgmHandle handle,
      struct ndb_mgm_loglevel* loglevel,
      unsigned int size
    )
Parameters. 
            ndb_mgm_get_clusterlog_loglevel() takes
            the following parameters:
            
                  A management handle
                  (NdbMgmHandle).
                
                  A loglevel (log level)
                  vector consisting of twelve elements, each of which is
                  an ndb_mgm_loglevel structure and
                  which represents a log level of the corresponding
                  category.
                
                  The size of the vector
                  (MGM_LOGLEVELS).
                
Return value. 
            This function returns the number of returned loglevels or
            -1 in the event of an error.
          
            Prior to MySQL 5.1.14, this function was known as
            ndb_mgm_get_loglevel_clusterlog(), and
            had the following signature:
const unsigned int* ndb_mgm_get_loglevel_clusterlog
    (
      NdbMgmHandle handle
    )
            This version of the function is now deprecated, but is still
            available for backward compatibility; however, in new
            applications, it is recommended that you use
            ndb_mgm_get_clusterlog_loglevel(), since
            it is thread-safe, and the older function is not.
