I think it would suffice for daemonize to wrap the call to the daemon's main procedure in a dynamic-wind block and call the cleanup function from the exit thunk. Unless the daemon procedure terminates itself with a low-level _exit or by sending itself a kill signal, the cleanup code should then always be executed. cu, Thomas _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
