27.Dt PMAP_MINCORE 9
28.Os
29.Sh NAME
30.Nm pmap_mincore
31.Nd determine if a virtual address is resident in physical memory
32.Sh SYNOPSIS
33.In sys/param.h
34.In vm/vm.h
35.In vm/pmap.h
36.Ft int
37.Fn pmap_mincore "pmap_t pmap" "vm_offset_t addr"
38.Sh DESCRIPTION
39The
40.Fn pmap_mincore
41function determines if the page at the virtual address
42.Fa addr
43in the physical map
44.Fa pmap
45is resident in physical memory.
46It is the machine-dependent interface used by the
47.Xr mincore 2
48system call.
49.Sh RETURN VALUES
50If the page is resident in physical memory,
51a mask of flags is returned,
52whose meaning is documented in
53.Xr mincore 2 ;
54otherwise,
550
56is returned.
57.Pp
58The
59.Fa pmap
60must exist and
61.Fa addr
62must be mapped into the
63.Fa pmap .
64If any error occurs, the machine-dependent implementation should
65return
660.
