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. The pmap must exist and addr must be mapped into the pmap. If any error occurs, the machine-dependent implementation should return 0. SEE ALSO mincore(2), pmap(9) AUTHORS
