Hi

This is a general question about using FIFO for interprocess communication.

Case:

Two processes A and B running in the same host want to communcate with each other. A sends a string of characters to B for processing. For this, a FIFO can be used as a communication mechanism. But the same thing can be achieved by using a FILE in append mode as a medium of communication. B (or even multiple processes) can open in append mode to write at the end of file and A can open in append mode itseld to read. If this is the case, which would be the ideal option to use in terms of simplicity in coding, in terms of performance etc? FIFO or a normal file?

Thanks,

You may want to look into dbus, which is designed to streamline inter-process communication (though the dbus daemon needs to be running). Another option would be to create a shared memory mapping by mmapping a file, though that could get really complex. Either of these options would require that both programs use dbus/mmapping respectively.

Sorry I don't have clear details about the FIFO option, but hopefully the next poster will
