- All Known Implementing Classes:
ExtentCommit
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
Instances of this interface may be set to the
ExtentHooks
struct.

invoke
boolean invoke(long extent_hooks, long addr, long size, long offset, long length, int arena_ind) 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 givenaddr
andsize
atoffset
bytes, extending forlength
on behalf of arenaarena_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.
