BoehmAllocator

Allocator for BDWGC-managed memory, implementing IAllocator. Thread-safe and compatible with -betterC. Requires thread registration for multi-threaded use when GCThreads is enabled.

struct BoehmAllocator {

enum uint alignment;

void[] allocate(size_t bytes);

void[] alignedAllocate(size_t bytes, uint a);

bool deallocate(void[] b);

bool reallocate(void[] b, size_t newSize);

void[] allocateZeroed(size_t bytes);

void enableIncremental();

void disable();

void collect();

bool isHeapPtr(void* ptr);

bool owns(void[] b);

size_t goodAllocSize(size_t n);

Functions

alignedAllocate void[] alignedAllocate(size_t bytes, uint a): Allocates aligned memory using GC_memalign, returns null if allocation fails
allocate void[] allocate(size_t bytes): Allocates memory of specified size, returns null if allocation fails
allocateZeroed void[] allocateZeroed(size_t bytes): Allocates zero-initialized memory
collect void collect(): Triggers garbage collection
deallocate bool deallocate(void[] b): Deallocates memory, safe for null buffers
disable void disable(): Disables garbage collection
enableIncremental void enableIncremental(): Enables incremental garbage collection
goodAllocSize size_t goodAllocSize(size_t n): Suggests a good allocation size
isHeapPtr bool isHeapPtr(void* ptr): Checks if pointer is GC-managed
owns bool owns(void[] b): Checks if the allocator owns the memory block
reallocate bool reallocate(void[] b, size_t newSize): Reallocates memory to new size, handles zero-size deallocation
