Summary

This chapter introduced the mailslot networking technology, which provides an application with simple one-way interprocess data communication using the Windows redirector. One of the most useful features of mailslots is that they allow you to broadcast a message to one or more computers over a network. However, because of the broadcast capability, mailslots do not provide reliable data transmission. If you want reliable data communication using the Windows redirector, consider using named pipes, the focus of our next chapter.
