Module malloc_ms_util 

Using malloc as mark sweep free-list allocator.

Functions

align_alloc

Allocate with alignment. This also guarantees the memory is zero initialized.

align_offset_alloc

Allocate with alignment and offset. Beside returning the allocation result, this will store the malloc result at (result - BYTES_IN_ADDRESS) so we know the original malloc result.

alloc

allocate size bytes, which is aligned to align at offset return the address, and whether it is an offset allocation

free^⚠

get_malloc_usable_size

get malloc usable size of an address is_offset_malloc: whether the address is allocated with some offset

offset_free

Free an address that is allocated with an offset (returned by crate::util::malloc::malloc_ms_util::align_offset_alloc).

offset_malloc_usable_size

Get the malloc usable size for an address that is returned by crate::util::malloc::malloc_ms_util::align_offset_alloc.
