The
pmap_mincore ();
function determines if the page at the virtual address
Fa addr
in the physical map
Fa 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
Fa pmap
must exist and
Fa addr
must be mapped into the
Fa pmap .
If any error occurs, the machine-dependent implementation should
return
0.
