VM_MAP_INHERIT(9)      FreeBSD Kernel Developer's Manual     VM_MAP_INHERIT(9)

NAME
     vm_map_inherit -- set fork	inheritance flags for a	range within a map

SYNOPSIS
     #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);

DESCRIPTION
     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.

IMPLEMENTATION NOTES
     The vm_map_inherit() function obtains a lock on the map using
     vm_map_lock(9) for	the duration of	the function.

RETURN VALUES
     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.
