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