sorry! i didn't make it clearly. this example locates in in section 7.3.2 in Maemo_Diablo_Reference_Manual_for_maemo_4.1. when the program try to initialize osso context using 'osso_initialize()', the return value is null, so the program corrupted. by the way, i run the program in scratchbox using the command 'run-standalone.sh ./libosso-rpc-sync'. thanks!
