    NAME

    
    
    vm_map_lookup
    
     
    vm_map_lookup_done
    
     - lookup the vm_object backing a given virtual region
    
     
    

    SYNOPSIS

       #include <sys/param.h>
       #include <vm/vm.h>
       #include <vm/vm_map.h>
    int Fo vm_map_lookup Fa vm_map_t *var_map vm_offset_t vaddr vm_prot_t fault_type Fa vm_map_entry_t *out_entry vm_object_t *object vm_pindex_t *pindex Fa vm_prot_t *out_prot boolean_t *wired Fc Ft void vm_map_lookup_done (vm_map_t map vm_map_entry_t entry);
     

    DESCRIPTION

    The vm_map_lookup ();
    function attempts to find the Vt vm_object , page index and protection, for the given virtual address Fa vaddr , in the map Fa var_map , assuming a page fault of the type Fa fault_type had occurred.

    Return values are guaranteed until vm_map_lookup_done ();
    is called to release the lock.  

    IMPLEMENTATION NOTES

    The function vm_map_lookup ();
    acquires a read-lock on the map Fa *var_map , but does not release it. The caller should invoke vm_map_lookup_done ();
    in order to release this lock.  

    RETURN VALUES

    The vm_map_lookup ();
    function returns KERN_SUCCESS and sets the Fa *object , Fa *pindex , Fa *out_prot , and Fa *out_entry arguments appropriately for the hypothetical page fault.
