Variants

MADV_NORMAL

No further special treatment. This is the default.

MADV_RANDOM

Expect random page references.

MADV_SEQUENTIAL

Expect sequential page references.

MADV_WILLNEED

Expect access in the near future.

MADV_DONTNEED

Do not expect access in the near future.

MADV_FREE

Specify that the application no longer needs the pages in the given range.

MADV_NOSYNC

Request that the system not flush the current range to disk unless it needs to.

MADV_AUTOSYNC

Undoes the effects of MADV_NOSYNC for any future pages dirtied within the given range.

MADV_NOCORE

Region is not included in a core file.

MADV_CORE
