    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 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.  

    SEE ALSO

    mincore(2), pmap(9)
