29.Dt PMAP_MINCORE 9
30.Os
31.Sh NAME
32.Nm pmap_mincore
33.Nd determine if a virtual address is resident in physical memory
34.Sh SYNOPSIS
35.In sys/param.h
36.In vm/vm.h
37.In vm/pmap.h
38.Ft int
39.Fn pmap_mincore "pmap_t pmap" "vm_offset_t addr"
40.Sh DESCRIPTION
41The
42.Fn pmap_mincore
43function determines if the page at the virtual address
44.Fa addr
45in the physical map
46.Fa pmap
47is resident in physical memory.
48It is the machine-dependent interface used by the
49.Xr mincore 2
50system call.
51.Sh RETURN VALUES
52If the page is resident in physical memory,
53a mask of flags is returned,
54whose meaning is documented in
55.Xr mincore 2 ;
56otherwise,
570
58is returned.
59.Pp
60The
61.Fa pmap
62must exist and
63.Fa addr
64must be mapped into the
65.Fa pmap .
66If any error occurs, the machine-dependent implementation should
67return
680.
