We have participated in OS DAY 2017 conference
The Baigudin Software Company has participated in OS DAY – a fourth scientific-practical conference, which aims to determine a mission of Russia in developing sphere of operating systems.
Class «util::Heap»
Heap memory.
Hardware address for system heap memory has to be aligned to eight.

public:
Heap(int64 size, ::api::Toggle*& sw);
virtual void* alloc(size_t size, void* ptr);
virtual bool isConstructed() const;
public: Heap(int64 size, ::api::Toggle*& sw);
Constructor.
Reference to global interrupt interface pointer is used for a possibility to change a value of that pointer. Until that pointer is NULL global interrupt is not used. This gives you a possibility to change using global interrupts on fly.
Parameters:
size — total heap size.
sw — reference to global interrupt toggle interface.
public: virtual ~Heap();
Destructor.
public: virtual void* alloc(size_t size, void* ptr);
Allocates memory.
Parameters:
size — required memory size in byte.
ptr — NULL value becomes to allocate memory, and other given values are simply returned as memory address.
Returns:
pointer to allocated memory or NULL.
public: virtual void free(void* ptr);
Frees an allocated memory.
Parameters:
ptr — pointer to allocated memory.
public: virtual bool isConstructed() const;
Tests if this object has been constructed.
Returns:
true if object has been constructed successfully.
public: static bool isObject(const Type* obj);
Tests if given object has been constructed object.
Parameters:
obj — pointer to object.
Returns:
true if object has been constructed successfully.
public: void* operator new(size_t, void* ptr);
Operator new.
Method initiates a building of heap memory checks and tests self memory structure data and leads to call the class constructor.
Parameters:
size — unused.
ptr — aligned to eight memory address.
Returns:
address of memory or NULL.
