The IPC mechanism is mach ports. The security goal for the IPC system is each end of the communication establishing the validity of the other. The server establishes the validity of a client using the mach_msg_audit_trailer_t structure to retrieve the PID of the sender and validate its code signature. What I want to do with the client is establish the validity of the server on startup. So far, my code reads: pid_t pid; mach_port_t port; name_t name = "com.mycompany.myportname"; bootstrap_look_up(bootstrap_port, name, &port); pid_for_task(port, &pid); printf("the server pid is %d\n", pid); I had rather hoped that this would work, but after some research I realize that it makes no sense. I'm beginning to think there is no way to do what I want. Any ideas?
