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