Expand description

File or memory access pattern advisory information.

Variants§

§

Normal

The application has no advice to give on its behavior with respect to the specified data.

§

Sequential

The application expects to access the specified data sequentially from lower offsets to higher offsets.

§

Random

The application expects to access the specified data in a random order.

§

WillNeed

The application expects to access the specified data in the near future.

§

DontNeed

The application expects that it will not access the specified data in the near future.

§

NoReuse

The application expects to access the specified data once and then not reuse it thereafter.
