addr in the physical map pmap is resident in physical memo
- ry. It is the
machine-dependent interface used by the mincore(2) system
- call.
RETURN VALUES
- If the page is resident in physical memory, a mask of flags
- is returned,
whose meaning is documented in mincore(2); otherwise, 0 is
- returned.
