I've read the fifo documentation and still have one question:
if I define a handler for a fifo, does it get called when a
user-process tries to read from the fifo or after it succeeds?
I'd really like it to be when the program tries, even if it blocks
(temporarily) so it can be used as a data-on-demand source. I know I could
always create a real driver which blocks a user-task until data is
available, but I'd rather have the simpler fifo mechanism. BTW, I expect
that data would be available around 1300 Hz (just a single longword).
I'd appreciate all info on the fifo's and any other suggestions about how I
can implement this in an efficient way.
