Doc from org.lwjgl.system.jemalloc.ExtentCommitI.invoke. Extent commit hook. An extent commit function conforms to the `extent_commit_t` type and commits zeroed physical memory to back 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. Committed memory may be committed in absolute terms as on a system that does not overcommit, or in implicit terms as on a system that overcommits and satisfies physical memory needs on demand via soft page faults. If the function returns true, this indicates insufficient physical memory to satisfy the request. Annotations @Override
