Data Structures
struct	header_s
	Each block allocated needs to remember its size, so we add a header to keep it in. HEADER_BLOCK and BLOCK_HEADER translate between a pointer to the header and a pointer to the block (what the caller of malloc gets). More...

Macros
#define	OTHER_MEMORY_IN_BYTES   ((size_t)74 * (size_t)1024 * (size_t)1024)
#define	OTHER_ADDRESS_SPACE_IN_BYTES   ((size_t)24 * (size_t)1024 * (size_t)1024)

Typedefs
typedef struct header_s	header_s
	Each block allocated needs to remember its size, so we add a header to keep it in. HEADER_BLOCK and BLOCK_HEADER translate between a pointer to the header and a pointer to the block (what the caller of malloc gets).

Functions
void	MemLogInit (const char *mps_log, unsigned long mps_telemetry)
	Set up the memory system to log to a file. More...
HqBool	MemInit (size_t *RIP_maxAddressSpaceInBytes, size_t *RIP_workingSizeInBytes, void *pMemory, SysMemFns *pSysMemFns)
	Initialise the memory arena and create the memory pool for use in skin. More...
void	MemFinish (int32 fError)
	Release the arena of managed memory. More...
void *	MemAlloc (size_t cbSize, HqBool fZero, int actionOnFail)
	Allocate a block of memory for use by the skin layer. More...
void *	MemRealloc (void *ptr, size_t cbSize)
	Reallocate a block of memory that was allocated by a prior call to MemAlloc(). More...
void	MemFree (void *ptr)
	Free a block of memory that was allocated by a prior call to MemAlloc(). More...
void *	SysAlloc (size_t cbSize)
	Allocate a block of system memory for use by the skin layer. More...
void	SysFree (void *ptr)
	Free a block of memory that was allocated by a prior call to SysAlloc(). More...
mps_arena_t	MemGetArena (void)
	Returns the single arena of managed memory that is shared between the core RIP and the skin layer.
size_t	GetPeakArenaSize (void)
	Obtain the peak arena size in bytes. More...
size_t	GetArenaCommitLimit (void)
	Obtain the commit limit of the arena in bytes. More...

Variables
static mps_arena_t	mem_arena = ((void*)0)
	The single MPS arena used by both core and skin.
static mps_pool_t	skin_pool = ((void*)0)
	The memory pool for use in skin.

OTHER_ADDRESS_SPACE_IN_BYTES

#define OTHER_ADDRESS_SPACE_IN_BYTES   ((size_t)24 * (size_t)1024 * (size_t)1024)

Address space left for other allocations (libraries).

OTHER_MEMORY_IN_BYTES

#define OTHER_MEMORY_IN_BYTES   ((size_t)74 * (size_t)1024 * (size_t)1024)

Memory left for other allocations (OS and libraries).
