Question

I have a process that continuously needs to write information. Furthermore, there is a second process which sometimes connects to the “information channel” of the writing process and should read the information that are written since it’s connected. This process might also deconnect and reconnect several times again.

I am currently realizing this with a named pipe, by using mkfifo() in my c++ program. Unfortunately if I call open() on this fifo it blocks until a process opens the fifo for reading. This is quite normal for named pipes, but I need this open command to be non-blocking.

Do you know an alternative to mkfifo in this case?

You could use Unix-domain sockets, or regular TCP sockets on loopback interface.
