what's pio.h?


So I see that we install machine/pio.h which defines functions like
these (amd64):

inb, insb, inw, insw, inl, insl; outb, outsb, ...

But I can't seem to find any documentation or implementation for this.

Is this in libc or does one need to link a library for these?
What are they good for?
