Classes
struct	Memory::TotalMemoryStatus
	Get the system's total current memory, this does not only include Nebula's memory allocations but the memory usage of the entire system. More...

Namespaces
namespace	Memory

Macros
#define	__MEMORY_CHECKPOINT(s)
	Debug and memory validation functions.
#define	__MEMORY_VALIDATE(s)
#define	n_new(type)
#define	n_new_array(type, size)
#define	n_delete(ptr)
#define	n_delete_array(ptr)

Functions
void *	Memory::Alloc (HeapType heapType, size_t size, size_t alignment)
	Allocate a block of memory from one of the global heaps.
void *	Memory::Realloc (HeapType heapType, void *ptr, size_t size)
	Re-Allocate a block of memory from one of the global heaps.
void	Memory::Free (HeapType heapType, void *ptr)
	Free a block of memory.
char *	Memory::DuplicateCString (const char *from)
	Duplicate a 0-terminated string, this method should no longer be used!
bool	Memory::IsOverlapping (const unsigned char *srcPtr, size_t srcSize, const unsigned char *dstPtr, size_t dstSize)
	Test if 2 areas of memory areas are overlapping.
void	Memory::Copy (const void *from, void *to, size_t numBytes)
	Copy a chunk of memory (note the argument order is different from memcpy()!!!)
void	Memory::Clear (void *ptr, size_t numBytes)
	Overwrite a chunk of memory with 0's.
void	Memory::Fill (void *ptr, size_t numBytes, unsigned char value)
	Fill memory with a specific byte.
TotalMemoryStatus	Memory::GetTotalMemoryStatus ()
	Get the system's total memory status.
void *	operator new (size_t size)
	Replacement global new/delete operators.
void *	operator new (size_t size, size_t align)
void *	operator new[] (size_t size)
	Replacement global new[] operators.
void *	operator new[] (size_t size, size_t align)
void	operator delete (void *p)
	Replacement global delete operator.
void	operator delete[] (void *p)
	Replacement global delete[] operator.
