vm_map_submap
VM_MAP_SUBMAP(9) BSD Kernel Developer's Manual VM_MAP_SUBMAP(9)NAME
vm_map_submap -- create a subordinate map
SYNOPSIS
#include <sys/param.h>
#include <vm/vm.h>
#include <vm/vm_map.h>
int
vm_map_submap(vm_map_t map, vm_offset_t start, vm_offset_t end, vm_map_t submap);
DESCRIPTION
The vm_map_submap() function marks the range bounded by start and end within the map map as being handled by a subordinate map sub_map.
It is generally called by the kernel memory allocator.
IMPLEMENTATION NOTES
This function is for internal use only.
Both maps must exist. The range must have been created with vm_map_find(9) previously.
No other operations may have been performed on this range before calling this function. Only the vm_fault() operation may be performed
within this range after calling this function.
To remove a submapping, one must first remove the range from the parent map, and then destroy the sub_map. This procedure is not recom-
mended.
RETURN VALUES
The vm_map_submap() function returns KERN_SUCCESS if successful.
Otherwise, it returns KERN_INVALID_ARGUMENT if the caller requested copy-on-write flags, or if the range specified for the sub-map was out of
range for the parent map, or if a NULL backing object was specified.
