public boolean invoke(long extent_hooks, long addr, long size, long size_a, long size_b, boolean committed, int arena_ind) Implements org.lwjgl.system.jemalloc.ExtentSplitI.invoke. Doc from org.lwjgl.system.jemalloc.ExtentSplitI.invoke. Extent split hook. An extent split function conforms to the `extent_split_t` type and optionally splits an extent at given `addr` and `size` into two adjacent extents, the first of `size_a` bytes, and the second of `size_b` bytes, operating on `committed`/decommitted memory as indicated, on behalf of arena `arena_ind`, returning false upon success. If the function returns true, this indicates that the extent remains unsplit and therefore should continue to be operated on as a whole. Annotations @Override
