| Enumerator |
|---|
| mi_option_show_errors | Print error messages.
|
| mi_option_show_stats | Print statistics on termination.
|
| mi_option_verbose | Print verbose messages.
|
| mi_option_max_errors | issue at most N error messages
|
| mi_option_max_warnings | issue at most N warning messages
|
| mi_option_reserve_huge_os_pages | reserve N huge OS pages (1GiB pages) at startup
|
| 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. If false, also disables THP for the process.
|
| 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_eager_commit | eager commit segments? (after eager_commit_delay segments) (enabled by default).
|
| mi_option_eager_commit_delay | 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 | 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_limit_os_alloc | If set to 1, do not use OS memory for allocation (but only pre-reserved arenas)
|
| mi_option_max_segment_reclaim | 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 | allow to reclaim an abandoned segment on a free (=1)
|
| mi_option_purge_extend_delay | 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)
