public boolean invoke(long extent_hooks, long addr, long size, long offset, long length, int arena_ind) Implements org.lwjgl.system.jemalloc.ExtentDecommitI.invoke. Doc from org.lwjgl.system.jemalloc.ExtentDecommitI.invoke. 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.
