Selective distribution of messages using named pipes

摘要

Method and apparatus in a computer system for communicating messages between message sending and message receiving processes, without the need of providing a system registry of receiving processes and message types. A process wishing to receive messages of type X creates a named pipe having name X. A process wishing to send a message of type X to other interested processes in the system opens every instance of the name pipe X and writes the message to each instance. The system automatically alerts the receiving process on the other end of a pipe instance and, in response, the receiving process reads the message from the named pipe.
