Function Documentation

OSGetSharedData()

BOOL OSGetSharedData	(	OSSharedDataType	type,
		uint32_t	unk_r4,
		void **	outPtr,
		uint32_t *	outSize
	)

__OSRootLoadShared()

void __OSRootLoadShared

(

)

OSBlockMove()

void * OSBlockMove	(	void *	dst,
		const void *	src,
		uint32_t	size,
		BOOL	flush
	)

Moves chunks of memory around, similarly to memmove.

Overlapping source and destination regions are supported.

Parameters

dst	The destination address for the move.
src	The source address for the move.
size	The size of the data to be moved, in bytes.
flush	Whether to flush the data caches for the source and destination.

Returns

dst is returned.

Note

This function makes use of the cache to speed up the copy, so a flush is recommended.

OSBlockSet()

void * OSBlockSet	(	void *	dst,
		uint8_t	val,
		uint32_t	size
	)

Fills a chunk of memory with the given value, like memset.

Parameters

dst	Pointer to the memory to fill.
val	Byte value to be set.
size	Number of bytes to be set to val.

Returns

dst is returned.

OSAllocFromSystem()

void * OSAllocFromSystem	(	uint32_t	size,
		int	align
	)

OSFreeToSystem()

void OSFreeToSystem

(

void *

ptr

)

OSGetForegroundBucket()

BOOL OSGetForegroundBucket	(	uint32_t *	outAddr,
		uint32_t *	outSize
	)

Gets the location and size of the foreground bucket memory area.

Note

This function may not account for the system reserved portion of the foreground bucket. Consider using OSGetForegroundBucketFreeArea() instead.

Parameters

outAddr	Pointer to write the foreground bucket's address to.
outSize	Pointer to write the foreground bucket's size to.

Returns

true on success.

OSGetForegroundBucketFreeArea()

BOOL OSGetForegroundBucketFreeArea	(	uint32_t *	outAddr,
		uint32_t *	outSize
	)

Gets the location and size of the application-usable portion of the foreground bucket area.

Parameters

outAddr	Pointer to write the bucket area's address to.
outSize	Pointer to write the bucket area's size to.

Returns

true on success.

OSGetMemBound()

int OSGetMemBound	(	OSMemoryType	type,
		uint32_t *	outAddr,
		uint32_t *	outSize
	)

Gets the location and size of available memory areas.

Parameters

type	Type of memory to get information about. See OSMemoryType.
outAddr	Pointer to write the area's address to.
outSize	Pointer to write the area's size to.

Returns

0 on success, -1 otherwise.

__OSZeroProcessMemory()

void __OSZeroProcessMemory

(

uint32_t

proccesID

)

Zeros the memory for a given proccessID.

Works only inside the ROOT process.
