Check the implementation of these functions (dice/include/dice.h) to see which members of the CORBA_Server_Environment are set and cleared (to avoid interference with other surrounding Dice generated code).

Should I call some ipc error cleanup after ? Regards Marc ___ l4-hackers mailing list l4-hackers@os.inf.tu-dresden.de http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers

This environment is passed to the error function. In the error function you could then check the partner member. Or, there is a user_data member in the CORBA_Server_Environment, which is of type void*. You could let it point to whatever data you need in the error function.

OK, I've tried to put this on an inherited interface. If I put it on the right interface, it's fine :). However, into error_function, I don't know how to get info on destination thread and call which generated error. Before reply call, I set a global variable to 0. error_function sets it to 1 if it is called. After reply call, I check this variable. If set to 1, I consider destination thread dead. Is there another way to do this less trickly ? Regards Marc ___ l4-hackers mailing list l4-hackers@os.inf.tu-dresden.de http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers
