+.Os
+.Sh NAME
+.Nm pmap_mincore
+.Nd determine if a virtual address is resident in physical memory
+.Sh SYNOPSIS
+.In sys/param.h
+.In vm/vm.h
+.In 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.
+.Pp
+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.
