Function Documentation

int sceKernelAllocateKTLS	(	int	id,
		int(*)(unsigned int *size, void *arg)	cb,
		void *	arg
	)

Setup the KTLS allocator.

Parameters:

	id	- The ID of the allocator
	cb	- The allocator callback
	arg	- User specified arg passed to the callback

Returns:

< 0 on error, allocation id on success

int sceKernelCheckThreadKernelStack

(

void

)

Check the thread kernel stack.

Returns:

Unknown

int sceKernelExtendKernelStack	(	int	type,
		void(*)(void *)	cb,
		void *	arg
	)

Extend the kernel thread stack.

Parameters:

	type	- The type of block allocation. One of PspSysMemBlockTypes
	cb	- A pointer to a callback function
	arg	- A pointer to a user specified argument

Returns:

< 0 on error

int sceKernelFreeKTLS

(

int

id

)

Free the KTLS allocator.

Parameters:

id

- The allocation id returned from AllocateKTLS

Returns:

< 0 on error

void* sceKernelGetKTLS

(

int

id

)

Get the KTLS of the current thread.

Parameters:

id

- The allocation id returned from AllocateKTLS

Returns:

The current KTLS, NULL on error

unsigned int sceKernelGetSyscallRA

(

void

)

Get the return address of the current thread's syscall.

Returns:

The RA, 0 on error

unsigned int sceKernelGetSystemStatusFlag

(

void

)

Get the system status flag.

Returns:

The system status flag

int sceKernelGetThreadKernelStackFreeSize

(

SceUID

thid

)

Get the free stack space on the kernel thread.

Parameters:

thid

- The UID of the thread

Returns:

The free stack space, < 0 on error

void* sceKernelGetThreadKTLS	(	int	id,
		SceUID	thid,
		int	mode
	)

Get the KTLS of a thread.

Parameters:

	id	- The allocation id returned from AllocateKTLS
	thid	- The thread is, 0 for current thread
	mode	- Perhaps? Sees to be set to 0 or 1

Returns:

The current KTLS, NULL on error

int sceKernelGetUserLevel

(

void

)

Get the user level of the current thread.

Returns:

The user level, < 0 on error

int sceKernelIsUserModeThread

(

void

)

Checks if the current thread is a usermode thread.

Returns:

0 if kernel, 1 if user, < 0 on error

int sceKernelSuspendAllUserThreads

(

void

)

Suspend all user mode threads in the system.

Returns:

0 on success, < 0 on error

int ThreadManForKernel_2D69D086	(	SceUID	uid,
		SceKernelThreadKInfo *	info
	)

Refer kernel version of thread information.

Parameters:

	uid	- UID to find
	info	- Pointer to info structure, ensure size is set before calling

Returns:

0 on success
