ExtentDecommitI (LWJGL 3.3.1 - jemalloc)

All Superinterfaces:

org.lwjgl.system.CallbackI, org.lwjgl.system.Pointer

All Known Implementing Classes:

ExtentDecommit

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface ExtentDecommitI
extends org.lwjgl.system.CallbackI
```
Instances of this interface may be set to the ExtentHooks struct.
Type
```

    Extent decommit hook.
    An extent decommit function conforms to the extent_decommit_t type and decommits any physical memory that is backing pages within an extent at given addr and size at offset bytes, extending for length on behalf of arena arena_ind, returning false upon success, in which case the pages will be committed via the extent commit function before being reused. If the function returns true, this indicates opt-out from decommit; the memory remains committed and available for future use, in which case it will be automatically retained for later reuse.
