Module allocator

Functions

mi_aligned_alloc^⚠

Allocate size bytes aligned by alignment with alignment as the first parameter.

mi_calloc^⚠

Allocate count items of size length each.

mi_calloc_aligned^⚠

Allocate size * count bytes aligned by alignment.

mi_calloc_aligned_at^⚠

Allocate size * count bytes aligned by alignment at a specified offset, zero-initialized.

mi_cfree^⚠

Checked free: If p came from mimalloc’s heap (as decided by mi_is_in_heap_region), this is [mi_free(p)], but otherwise it is a no-op.

mi_collect^⚠

Eagerly free memory.

mi_expand^⚠

Try to re-allocate memory to newsize bytes in place.

mi_free^⚠

Free previously allocated memory.

mi_free_aligned^⚠

Alignment-aware deallocation: Like mi_free, but accepts the size and alignment as well.

mi_free_size^⚠

Size-aware deallocation: Like mi_free, but accepts the size and alignment as well.

mi_free_size_aligned^⚠

Layout-aware deallocation: Like mi_free, but accepts the size and alignment as well.

mi_good_size^⚠

Return the used allocation size.

mi_is_in_heap_region^⚠

Returns true if this is a pointer into a memory region that has been reserved by the mimalloc heap.

mi_malloc^⚠

Allocate size bytes.

mi_malloc_aligned^⚠

Allocate size bytes aligned by alignment.

mi_malloc_aligned_at^⚠

Allocate size bytes aligned by alignment at a specified offset.

mi_malloc_small^⚠

Allocate an object of no more than MI_SMALL_SIZE_MAX bytes.

mi_mallocn^⚠

Allocate count items of size length each.

mi_posix_memalign^⚠

Allocate size of bytes aligned by alignment and place the address of the allocated memory to ptr.

mi_process_info^⚠

Return process information (time and memory usage). All parameters are optional (nullable) out-params:

mi_process_init^⚠

Initialize the process.

mi_realloc^⚠

Re-allocate memory to newsize bytes.

mi_realloc_aligned^⚠

Re-allocate memory to newsize bytes, aligned by alignment.

mi_realloc_aligned_at^⚠

Re-allocate memory to newsize bytes aligned by alignment at a specified offset.

mi_reallocf^⚠

Re-allocate memory to newsize bytes.

mi_reallocn^⚠

Re-allocate memory to count elements of size bytes.

mi_realpath^⚠

Resolve a file path name, producing a C string which can be passed to mi_free.

mi_recalloc^⚠

Zero initialized re-allocation, following calloc paramater conventions.

mi_recalloc_aligned^⚠

Aligned version of mi_recalloc.

mi_recalloc_aligned_at^⚠

Offset-aligned version of mi_recalloc.

mi_register_deferred_free^⚠

Register a deferred free function.

mi_register_error^⚠

Register an error callback function.

mi_register_output^⚠

Register an output function.

mi_rezalloc^⚠

Zero initialized re-allocation.

mi_rezalloc_aligned^⚠

Aligned version of mi_rezalloc.

mi_rezalloc_aligned_at^⚠

Offset-aligned version of mi_rezalloc.

mi_stats_merge^⚠

Merge thread local statistics with the main statistics and reset.

mi_stats_print^⚠

Print the main statistics.

mi_stats_print_out^⚠

Print the main statistics.

mi_stats_reset^⚠

Reset statistics.

mi_strdup^⚠

Allocate and duplicate a nul-terminated C string.

mi_strndup^⚠

Allocate and duplicate a nul-terminated C string, up to n bytes.

mi_thread_done^⚠

Uninitialize mimalloc on a thread.

mi_thread_init^⚠

Initialize mimalloc on a thread.

mi_thread_stats_print_out^⚠

Print out heap statistics for this thread.

mi_usable_size^⚠

Return the available bytes in a memory block.

mi_version^⚠

Return the mimalloc version number.

mi_zalloc^⚠

Allocate zero-initialized size bytes.

mi_zalloc_aligned^⚠

Allocate size bytes aligned by alignment, initialized to zero.

mi_zalloc_aligned_at^⚠

Allocate size bytes aligned by alignment at a specified offset, zero-initialized.

mi_zalloc_small^⚠

Allocate an zero-initialized object of no more than MI_SMALL_SIZE_MAX bytes.
