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.
