mi_option_reserve_huge_os_pages_at 

Reserve N huge OS pages at a specific NUMA node N.

mi_option_reserve_os_memory 

reserve specified amount of OS memory in an arena at startup (internally, this value is in KiB; use mi_option_get_size())

mi_option_allow_large_os_pages 

allow large (2 or 4 MiB) OS pages, implies eager commit.

mi_option_purge_decommits 

should a memory purge decommit? (=1). Set to 0 to use memory reset on a purge (instead of decommit)

mi_option_arena_reserve 

initial memory size for arena reservation (= 1 GiB on 64-bit) (internally, this value is in KiB; use mi_option_get_size())

mi_option_os_tag 

tag used for OS logging (macOS only for now) (=100)

mi_option_retry_on_oom 

retry on out-of-memory for N milli seconds (=400), set to 0 to disable retries. (only on windows)

mi_option_generic_collect 

collect heaps every N (=10000) generic allocation calls

mi_option_allow_thp 

allow transparent huge pages? (=1) (on Android =0 by default). Set to 0 to disable THP for the process.

mi_option_guarded_min 

only used when building with MI_GUARDED: minimal rounded object size for guarded objects (=0)

mi_option_guarded_max 

only used when building with MI_GUARDED: maximal rounded object size for guarded objects (=0)

mi_option_guarded_precise 

disregard minimal alignment requirement to always place guarded blocks exactly in front of a guard page (=0)

mi_option_guarded_sample_rate 

1 out of N allocations in the min/max range will be guarded (=1000)

mi_option_guarded_sample_seed 

can be set to allow for a (more) deterministic re-execution when a guard page is triggered (=0)

mi_option_eager_commit 

v1,v2: eager commit segments? (after eager_commit_delay segments) (enabled by default).

mi_option_eager_commit_delay 

v2: the first N segments per thread are not eagerly committed (but per page in the segment on demand)

mi_option_arena_eager_commit 

eager commit arenas? Use 2 to enable just on overcommit systems (=2)

mi_option_abandoned_page_purge 

v1,v2: immediately purge delayed purges on thread termination

mi_option_purge_delay 

memory purging is delayed by N milli seconds; use 0 for immediate purging or -1 for no purging at all. (=10)

mi_option_use_numa_nodes 

0 = use all available numa nodes, otherwise use at most N nodes.

mi_option_disallow_os_alloc 

1 = do not use OS memory for allocation (but only programmatically reserved arenas)

mi_option_max_segment_reclaim 

v2: max. percentage of the abandoned segments can be reclaimed per try (=10%)

mi_option_destroy_on_exit 

if set, release all memory on exit; sometimes used for dynamic unloading but can be unsafe

mi_option_arena_purge_mult 

multiplier for purge_delay for the purging delay for arenas (=10)

mi_option_abandoned_reclaim_on_free 

v1,v2: allow to reclaim an abandoned segment on a free (=1)

mi_option_purge_extend_delay 

v1,v2: extend purge delay on each subsequent delay (=1)

mi_option_disallow_arena_alloc 

1 = do not use arena's for allocation (except if using specific arena id's)

mi_option_visit_abandoned 

allow visiting heap blocks from abandoned threads (=0)

mi_option_target_segments_per_thread 

v1,v2: experimental (=0)

mi_option_page_reclaim_on_free 

v3: reclaim abandoned pages on a free (=0). -1 disallowr always, 0 allows if the page originated from the current theap, 1 allow always

mi_option_page_full_retain 

v3: retain N full (small) pages per size class (=2). Use -1 for infinite (as in v1,v2).

mi_option_page_max_candidates 

v3: max candidate pages to consider for allocation (=4)

mi_option_max_vabits 

v3: max user space virtual address bits to consider (=48)

mi_option_pagemap_commit 

v3: commit the full pagemap (to always catch invalid pointer uses) (=0)

mi_option_page_commit_on_demand 

v3: commit page memory on-demand (=0)

mi_option_page_max_reclaim 

v3: don't reclaim pages of the same originating theap if we already own N pages (in that size class) (=-1 (unlimited))

mi_option_page_cross_thread_max_reclaim 

v3: don't reclaim pages across threads if we already own N pages (in that size class) (=16)

mi_option_minimal_purge_size 

v3: set minimal purge size (in KiB) (=0). By default set to either 64 or 2048 if THP is enabled. (internal value is in KiB so use mi_option_get_size())

mi_option_arena_max_object_size 

v3: set maximal object size that can be allocated in an arena (in KiB) (=2GiB on 64-bit).
