hi.
i wrote a program to control a device attached to the serial port of my
computer. the program works fine but it is meant to work together
alongside with other programs. at first i was just going to have the
other programs run the control program. this would work fine but then, i
thought that a more elegant solution would be to have the other programs
communicate with this one through UNIX IPC.
what i need to know is what type of IPC would be best. my control
program would only need to receive short messages (~5 bytes) and then
control the serial port based on those messages. i was thinking that a
message queue would be best but perhaps one of the experts here feels
that a shared memory segment or a FIFO would be better?
thanks in advance.
