  * Each MGM API function needs a management server handle
- * of type Mgm_C_Api::NdbMgmHandle.  
+ * of type <code>Mgm_C_Api::NdbMgmHandle</code>.
  * This handle is initally created by calling the
- * function ndb_mgm_create_handle().
+ * function <code>ndb_mgm_create_handle()</code>.
  *
  * A function can return:
  *  -# An integer value.
- *     A value of -1 indicates an error.
- *  -# A pointer value.  A NULL value indicates an error;
- *     Otherwise, the return value must be free()ed by the user of the MGM API.
+ *     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 <code>free()</code>ed by the user of the MGM API.
  *
  * Error conditions can be identified by using the appropriate
  * error-reporting functions.
