unsigned int	sceKernelGetSyscallRA (void)
	Get the return address of the current thread's syscall.
int	sceKernelGetThreadKernelStackFreeSize (SceUID thid)
	Get the free stack space on the kernel thread.
int	sceKernelCheckThreadKernelStack (void)
	Check the thread kernel stack.
int	sceKernelExtendKernelStack (int type, void(*cb)(void *), void *arg)
	Extend the kernel thread stack.
unsigned int	sceKernelGetSystemStatusFlag (void)
	Get the system status flag.
int	sceKernelAllocateKTLS (int id, int(*cb)(unsigned int *size, void *arg), void *arg)
	Setup the KTLS allocator.
int	sceKernelFreeKTLS (int id)

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
