63 the mailslot code keeps a list of mailslot handlers. A mailslot
64 handler is a function that receives incoming packets for a specific
65 mailslot name. When a caller needs to send a mailslot and wants to
66 get a reply then it needs to register itself as listening for
67 incoming packets on the reply mailslot
