-# lmemorymanager
-
-Compatibility shim that re-exports the `memory.heap` API under the legacy unit name.
-
-## Overview
-
-The Wasuro WASM VM project references the old unit name `lmemorymanager` for heap memory operations. Because the Wasuro source tree cannot be modified, this shim unit re-exports every public symbol from `memory.heap` so that `uses lmemorymanager` continues to compile without changes. All functions are thin inline wrappers that delegate directly to their `memory.heap` counterparts.
-
-## Dependencies
-
-- `memory.heap` -- the canonical heap allocator implementation in the Asuro kernel.
-
-## Constants
-
-### ALLOC_UNIT
-Re-exported from `memory.heap.ALLOC_UNIT`. The base allocation unit size used by the heap allocator.
-
-### DATA_OFFSET
-Re-exported from `memory.heap.DATA_OFFSET`. Byte offset from a heap block header to the start of user data.
-
-### PAGE_SIZE_LMM
-Re-exported from `memory.heap.PAGE_SIZE_LMM`. Page size used by the lightweight memory manager.
-
-### TOTAL_UNITS
-Re-exported from `memory.heap.TOTAL_UNITS`. Total number of allocation units per heap page.
-
-### BITMAP_DWORDS
-Re-exported from `memory.heap.BITMAP_DWORDS`. Number of 32-bit words in the per-page allocation bitmap.
-
-### SIZE_PREFIX
-Re-exported from `memory.heap.SIZE_PREFIX`. Size of the prefix stored before each allocation to record its length.
-
-### LARGE_ALLOC_MAGIC
-Re-exported from `memory.heap.LARGE_ALLOC_MAGIC`. Magic value used to identify large (multi-page) allocations.
-
-## Types
-
-### PHeapPageHeader / THeapPageHeader
-Re-exported from `memory.heap`. Pointer and record types describing the header structure at the beginning of each heap page.
-
-## Functions and Procedures
-
-### init
-```pascal
-procedure init;
-```
-Initializes the heap memory manager by delegating to `memory.heap.init`.
-
-### kalloc
-```pascal
-function kalloc(size: uint32): void;
-```
-Allocates `size` bytes from the kernel heap and returns a pointer to the allocated memory.
-
-### klalloc
-```pascal
-function klalloc(size: uint32): void;
-```
-Performs a large kernel allocation of `size` bytes and returns a pointer to the allocated memory.
-
-### klfree
-```pascal
-procedure klfree(address: uint32);
-```
-Frees a large allocation previously obtained via `klalloc`.
-
-### kpalloc
-```pascal
-function kpalloc(address: uint32): void;
-```
-Allocates a heap page at the specified address and returns a pointer to it.
-
-### kfree
-```pascal
-procedure kfree(area: void);
-```
-Frees a standard allocation previously obtained via `kalloc`.
-
-### lmm_total_free
-```pascal
-function lmm_total_free: uint32;
-```
-Returns the total number of free bytes available across all heap pages.
-
-### lmm_page_count
-```pascal
-function lmm_page_count: uint32;
-```
-Returns the current number of heap pages managed by the allocator.
-
-## Notes
-
-- Every function and procedure in the implementation section is marked `inline`, so the compiler eliminates the wrapper overhead entirely.
-- This unit exists solely for backward compatibility with the Wasuro WASM VM build. New kernel code should use `memory.heap` directly.
