SYNOPSIS


.In sys/param.h
.In vm/vm.h
.In vm/pmap.h int pmap_mincore "pmap_t pmap" "vm_offset_t addr"

DESCRIPTION

The pmap_mincore function determines if the page at the virtual address addr in the physical map pmap is resident in physical memory. 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.
