vm_map_inherit —
set fork inheritance flags for a range within a
map
#include
<sys/param.h>
#include <vm/vm.h>
#include <vm/vm_map.h>
int
vm_map_inherit(vm_map_t map,
vm_offset_t start, vm_offset_t
end, vm_inherit_t new_inheritance);
The
vm_map_inherit()
function sets the inheritance flags for the range
start to end within the target
map to the value
new_inheritance.
The new_inheritance flag must have one of
the values VM_INHERIT_NONE,
VM_INHERIT_COPY, or
VM_INHERIT_SHARE. This affects how the map will be
shared with child maps when the associated process forks.
The vm_map_inherit() function obtains a
lock on the map using vm_map_lock(9)
for the duration of the function.
The vm_map_inherit() function returns
KERN_SUCCESS if the inheritance flags could be set.
Otherwise, if the provided flags were invalid,
KERN_INVALID_ARGUMENT will be returned.
