VM_MAP_INSERT(9) BSD Kernel Developer's Manual VM_MAP_INSERT(9)NAMEvm_map_insert — insert an object into a map
SYNOPSIS
#include <sys/param.h>
#include <vm/vm.h>
#include <vm/vm_map.h>
int
vm_map_insert(vm_map_t map, vm_object_t object, vm_ooffset_t offset,
vm_offset_t start, vm_offset_t end, vm_prot_t prot, vm_prot_t max,
int cow);
DESCRIPTION
The vm_map_insert() function inserts a mapping for the entire vm_object
object into the target map map.
The offset argument specifies the offset into the object at which to
begin mapping. The object's size should match that of the specified
address range.
The start and end arguments specify the bounds of the mapped object's
window in the address space of map.
The cow argument specifies the flags which should be propagated to the
new entry, for example, to indicate that this is a copy-on-write mapping.
IMPLEMENTATION NOTES
This function implicitly creates a new vm_map_entry by calling the inter‐
nal function vm_map_entry_create(). This function may use the Giant lock
to ensure that only a single thread is present in the function.
RETURN VALUES
The vm_map_insert() function returns KERN_SUCCESS if the mapping could be
made successfully.
Otherwise, KERN_INVALID_ADDRESS will be returned if the start of the
range could not be found, or KERN_NO_SPACE if the range was found to be
part of an existing entry or if it overlaps the end of the map.
