As the function is inlined, its implementation is in the very same header file (pkg/l4sys/include/ipc.h). It just returns the error code, stored in the utcb, which was set during IPC. > 2.l4_ipc_error( ),return 4,i look up in l4re document it means > L4_ENOT_EXISTENT.but how can i solve that? The documentation in the header file (pkg/l4sys/include/ipc.h) is quite clear about the error source: L4_IPC_ENOT_EXISTENT = 0x04, /**< Non-existing destination or source. could you please give us a minimal code example (including the lua script and both communcation partners) that causes this? You communication partner has probably terminated or something like that. - Marcus > thanks! > > 发自 Android 版 Yahoo! 邮箱 _______________________________________________ l4-hackers mailing list [email protected] http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers
