  description:  connect to DBMServer
  
                This function connects the client application with the specified 
                server.

                This function is UCS2 enabled for the usage as dbmapi.dll with 
                the DBMGui.

  arguments:    servernode [IN] - A pointer to a zero terminated string with the
                                  name of the server node. This string may be empty
                                  or the name of the local host for special local 
                                  communication. For real local TCP/IP communication 
                                  this string should be set to "localhost".
                dbname [IN]     - A pointer to a zero terminated string with the
                                  database name. This string maybe empty. If a 
                                  database ist spedcified the DBMServer receives this
                                  name as a special argument. The XServer checks the
                                  version of the database and starts the correct
                                  DBMServer.
                dbroot [IN]     - A pointer to a zero terminated string with an 
                                  installation path. The DBMServer at this path will
                                  be used. If there is a dbname specified, this 
                                  parameter will be ignored.
                sessionOUT [OUT]- A pointer to a buffer for the session pointer. 
                                  The returned pointer should be used for any 
                                  subsequent DBM-API call.
