Detailed Description

This module contains routines to threads in the kernel.

Typedef Documentation

SceKernelThreadKInfo

typedef struct SceKernelThreadKInfo SceKernelThreadKInfo

Structure to hold the status information for a thread (kernel form) 1.5 form.

Function Documentation

sceKernelAllocateKTLS()

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

sceKernelCheckThreadKernelStack()

int sceKernelCheckThreadKernelStack

(

void

)

Check the thread kernel stack.

Returns

Unknown

sceKernelExtendKernelStack()

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

sceKernelFreeKTLS()

int sceKernelFreeKTLS

(

int

id

)

Free the KTLS allocator.

Parameters

id	- The allocation id returned from AllocateKTLS

Returns

< 0 on error

sceKernelGetKTLS()

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

sceKernelGetSyscallRA()

unsigned int sceKernelGetSyscallRA

(

void

)

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

Returns

The RA, 0 on error

sceKernelGetSystemStatusFlag()

unsigned int sceKernelGetSystemStatusFlag

(

void

)

Get the system status flag.

Returns

The system status flag

sceKernelGetThreadKernelStackFreeSize()

int sceKernelGetThreadKernelStackFreeSize

(

SceUID

thid

)

Get the free stack space on the kernel thread.

Parameters

	)

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

sceKernelGetUserLevel()
