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
	Allocates memory using the TLSF method (http://www.gii.upv.es/tlsf/files/ecrts04_tlsf.pdf), with extended handling of padding to better suit GPUs.

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.
