If <code>ReplyTarget</code> is not zero, a reply from the TLS will be sent to that session.

Then it will wait until either of the passed sessions has an incoming message, is closed, a passed port has an incoming connection, or the timeout expires.

If there is an incoming message, it is copied to the TLS.

After being validated, passed handles will be enumerated in order; even if a session has been closed, if one that appears earlier in the list has an incoming message, it will take priority and a result code of 0x0 will be returned.

=== Result codes ===

'''0x0:''' Success. Either a session has an incoming message or a port has an incoming connection. <code>HandleIndex</code> is set appropriately.

'''0xea01:''' Timeout. No handles were signalled before the timeout expired. <code>HandleIndex</code> is not updated.

'''0xf601:''' Port remote dead. One of the sessions has been closed. <code>HandleIndex</code> is set appropriately.
