NAME¶
pmap_mincore
—
determine if a virtual address is resident in
physical memory
SYNOPSIS¶
#include
<sys/param.h>
#include
<vm/vm.h>
#include
<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.
SEE ALSO¶

pmap(9)
