Depends.
That is one way. Another is to wrap your rtlinux task with a normal linux
device driver which can then communicate with users using ordinary
read/write/ioctl functions. You'd need some way to notify the rtlinux task
that there's something for it to do. If it's already a periodic task,
simple semaphores would suffice. Otherwise, a FIFO just for notification
would make the simplest user interface in terms of using familiar
functions.

Subject: [rtl] API to rtlinux programs
> Hi
> I am making a state machine as a realtime program, in RTLinux ver 3.1
> My program have to offer an API so that other programs can call some
functions inside my state machine.
> What is the right way to do this ? is the only way to make use of a
RT-FIFO and then make some kind of simple protocol (X means do this, Y
means do that), so that the user programs put messages into the RT-FIFO
which are read by the realtime program.
