Heap

This struct encapsulates heap manipulation functionality.

This struct is neither default constructable nor copyable. Pass it by ref to functions or use $(STDREF typecons, RefCounted).

struct Heap {

enum CreateOptions;

this(CreateOptions options, size_t initialSize, size_t maximumSize);

this(HANDLE heapHandle, bool own);

bool associated [@property getter];

HANDLE handle [@property getter];

bool ownHandle [@property getter];

void* alloc(size_t bytes, bool zeroMemory, Flags flags);

void* reAlloc(void* ptr, size_t bytes, bool zeroMemory, bool inPlaceOnly, Flags flags);

void free(void* p, Flags flags);

size_t size(void* p, Flags flags);

}

Constructors

this this(): Undocumented in source.
this this(CreateOptions options, size_t initialSize, size_t maximumSize): Construct a new Heap.
this this(HANDLE heapHandle, bool own): Construct a Heap from a heapHandle.

Destructor

~this ~this(): Undocumented in source.

Postblit

this(this) this(this): Undocumented in source.

Members

Enums

CreateOptions enum CreateOptions: Heap construction options.
Flags enum Flags: General heap usage flags.

Functions

alloc void* alloc(size_t bytes, bool zeroMemory, Flags flags): Allocates a block of memory.
free void free(void* p, Flags flags): Frees a block of memory.
reAlloc void* reAlloc(void* ptr, size_t bytes, bool zeroMemory, bool inPlaceOnly, Flags flags): Reallocates a block of memory (i.e. memory content is preserved).
size size_t size(void* p, Flags flags): Retrieves the size of an allocated from this heap memory block.

Properties

associated bool associated [@property getter]: Returns whether this is associated with a heap handle. It is asserted that no member functions are called for an unassociated Heap struct.
handle HANDLE handle [@property getter]: Gets the handle of the associated heap.
ownHandle bool ownHandle [@property getter]: Returns whether handle of the associated heap will be destroyed on destruction.
