long invoke(long extent_hooks, long new_addr, long size, long alignment, long zero, long commit, int arena_ind)Extent allocation hook.
An extent allocation function conforms to the
extent_alloc_ttype and upon success returns a pointer to
sizebytes of mapped memory on behalf of arena
arena_indsuch that the extent's base address is a multiple of
alignment, as well as setting
*zeroto indicate whether the extent is zeroed and
*committo indicate whether the extent is committed. Upon error the function returns
sizeparameter is always a multiple of the page size. The
alignmentparameter is always a power of two at least as large as the page size. Zeroing is mandatory if
*zerois true upon function entry. Committing is mandatory if
*commitis true upon function entry. If
NULL, the returned pointer must be
new_addron success or
NULLon error. 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. Note that replacing the default extent allocation function makes the arena's
