NAME

pmap_mincore - determine if a virtual address is resident in physical memory

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

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 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.
