outb() and hard-realtime

I'd like to call outb() from inside the cycle of a LXRT hard-realtime task
in userspace, to toggle a pin on the parallel port. I wonder if doing so
will force my task in soft-realtime.
I don't think so, because the in*(), out*() functions should expand to
inline calls to their equivalents, but I'd like a more informed answer.
Thanks in advance.
