NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

     #include <sys/param.h>
     #include <vm/vm.h>
     #include <vm/pmap.h>

     int
     pmap_mincore(pmap_t pmap, vm_offset_t addr);

DESCRIPTION    [Toc]    [Back]

     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 mincore(2) system call.

RETURN VALUES    [Toc]    [Back]

     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'.
