25 /* http://web.mit.edu/darwin/src/modules/xnu/osfmk/man/exc_server.html says:
26 The exc_server function is the MIG generated server handling function
27 to handle messages from the kernel relating to the occurrence of an
28 exception in a thread. Such messages are delivered to the exception port
29 set via thread_set_exception_ports or task_set_exception_ports. When an
30 exception occurs in a thread, the thread sends an exception message to its
31 exception port, blocking in the kernel waiting for the receipt of a reply.
32 The exc_server function performs all necessary argument handling for this
33 kernel message and calls catch_exception_raise, catch_exception_raise_state
34 or catch_exception_raise_state_identity, which should handle the exception.
35 If the called routine returns KERN_SUCCESS, a reply message will be sent,
36 allowing the thread to continue from the point of the exception; otherwise,
37 no reply message is sent and the called routine must have dealt with the
38 exception thread directly. */
