43 * Wait until a server is registered in naming service.
44 * \param serverName name of the server to find.
45 * When SALOME_NamingService is available,
46 * use NamingService_WaitForServerReadiness instead.
47 * This function is needed when macro MESSAGE used by SALOME_NamingService
48 * is not available (inside LocalTrace methods, for instance !).
49 * Direct access to CORBA Name Service. Look for serverName at Name service
50 * Root without extensions.
