+The type of exception message to be sent. Defined types are:
+<dl>
+<p>
+<dt> <strong>EXCEPTION_DEFAULT</strong>
+<dd>
+Send a <strong>catch_exception_raise</strong> message including the thread

+<p>
+<dt> <strong>EXCEPTION_DEFAULT_PROTECTED</strong>

+<dd>
+Send a <strong>catch_exception_raise_state_identity</strong> message
+including the thread identity and state.
+<p>
+<dt> <strong>EXCEPTION_STATE_IDENTITY_PROTECTED</strong>
+<dd>
+Send a <strong>catch_exception_raise_state_identity</strong> message
+including the thread identity and state. Mark the exception port
+(and associated exceptions) as protected.
+</dl>
+<p>
+<dt> <var>flavor</var>
+<dd>
+[in scalar]
+The type of state to be sent with the exception message.
+These types are defined in \*L<mach/thread_states.h>\*O.
+</dl>
+<h3>DESCRIPTION</h3>
+<p>
+The <strong>thread_set_exception_ports</strong> function sets a specified
+set of exception
+ports belonging to <var>thread</var>.
+<h3>NOTES</h3>
+<p>
+If the value of the <strong>EXC_MACH_SYSCALL</strong> exception class exception port is
+the host name port, Mach kernel traps are executed by the kernel as expected;
+any other value causes the attempted execution of these system call numbers to
+be considered an exception.
+<p>
+A "protected" exception port is one which cannot be fetched and for which
+exception processing cannot be aborted (<strong>thread_abort</strong>).
+<h3>RETURN VALUES</h3>
+<p>
+Only generic errors apply.
