.Dd July 21, 2003 .Dt PMAP_MINCORE 9 .Os .Sh NAME .Nm pmap_mincore .Nd determine if a virtual address is resident in physical memory .Sh SYNOPSIS n sys/param.h n vm/vm.h n vm/pmap.h .Ft int .Fn pmap_mincore "pmap_t pmap" "vm_offset_t addr" .Sh DESCRIPTION The .Fn 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 .Xr mincore 2 system call. .Sh RETURN VALUES If the page is resident in physical memory, a mask of flags is returned, whose meaning is documented in .Xr mincore 2 ; otherwise, 0 is returned.
p 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. .Sh SEE ALSO .Xr mincore 2 , .Xr pmap 9 .Sh AUTHORS This manual page was written by .An Bruce M Simpson Aq bms@spc.org .
