* The NDB Cluster Management API (MGM API) is a C API
* that is used to:
* - Start and stop database nodes (DB nodes)
* - Start and stop database nodes (ndbd processes)
* - Start and stop NDB Cluster backups
* - Control the NDB Cluster log
* - Perform other administrative tasks

* @section General Concepts
*
* Each MGM API function needs a management server handle
* of type Mgm_C_Api::NdbMgmHandle.
* of type @ref NdbMgmHandle.
* This handle is initally created by calling the
* function ndb_mgm_create_handle().
* function ndb_mgm_create_handle() and freed by calling
* ndb_mgm_destroy_handle().
*
* A function can return:
* -# An integer value.
* A value of <b>-1</b> indicates an error.
* -# A pointer value. A <var>NULL</var> value indicates an error;
* otherwise, the return value must be freed by the user of the MGM API.
* -# A non-const pointer value. A <var>NULL</var> value indicates an error;
* otherwise, the return value must be freed
* by the user of the MGM API
* -# A const pointer value. A <var>NULL</var> value indicates an error.
* Returned value should not be freed.
*
* Error conditions can be identified by using the appropriate
* error-reporting functions.
* error-reporting functions ndb_mgm_get_latest_error() and
* @ref ndb_mgm_error.
