Re^2: Sending commands to another process that isn't expecting it

The process issuing the commands to the daemon will not be a parent of the daemon.

Should I just send a SIGUSR1 to the daemon process using kill and then in the handler for SIGUSR1 in the daemon have it check a fifo file for input?

There isn't such a thing as a bidirectional FIFO is there? I tried opening both FIFOs as "+<" but it didn't work as expected. I suppose if I want the daemon to communicate back and send an "OK" message or anything I'd have to switch up the read/write mode on both ends?	[reply]
