Function Documentation

SetBreak()

static void* SetBreak ( const unsigned int  increment, AllocationMap *const  map  )

static

Set break position of a memory region.

Parameters

increment	The number of bytes to increment the break.
map	A pointer to the concerned allocation map.

Returns

A pointer to the beginning of the allocated memory block, or NULL if can't set break, or the current break position if increment is zero.

Definition at line 34 of file memory.c.

KIncrementalMalloc()

void* KIncrementalMalloc

(

const size_t

size

)

Allocate memory for kernel objects using incremental method.

Parameters

size	The size in bytes to allocate.

Returns

A pointer to the allocated region, or NULL if allocation is impossible.

Definition at line 67 of file memory.c.

Memory_Copy()

void Memory_Copy	(	const void *	source,
		void *	destination,
		const size_t	size
	)

Copy bytes from one location to another in main memory.

Parameters

source	A pointer to the source address in RAM.
destination	A pointer to the destination address in RAM.
size	The number of bytes to copy.
