Function Documentation

◆ attribute()

__attribute__ ( (__noreturn__) )

Terminates execution after a stack-protector check fails.

◆ sceKernelBacktrace()

SceInt32 sceKernelBacktrace	(	SceUID	thread_id,
		SceKernelCallFrame *	call_frame_buffer,
		SceSize	num_bytes_buffer,

		SceInt32	mode
	)

Gets a thread backtrace.

Parameters

[in]	thread_id	Thread ID, or SCE_KERNEL_BACKTRACE_CONTEXT_CURRENT.
[out]	call_frame_buffer	Buffer that receives the call frames, or NULL when num_bytes_buffer is 0.
[in]	num_bytes_buffer	Size of the call-frame buffer in bytes. A non-NULL buffer must hold at least one frame.
[out]	num_frames	Optional pointer that receives the number of frames written to the output buffer.
[in]	mode	Bitwise OR of SceKernelBacktraceMode values.

Returns: With SCE_KERNEL_BACKTRACE_MODE_DONT_EXCEED, 0 on success. Otherwise, the complete call-stack depth on success, even when the output buffer is too small to contain every frame. Returns < 0 on error.

◆ sceKernelBacktraceSelf()

Parameters

[out]	call_frame_buffer	Buffer that receives the call frames, or NULL when num_bytes_buffer is 0.
[in]	num_bytes_buffer	Size of the call-frame buffer in bytes. A non-NULL buffer must hold at least one frame.
[out]	num_frames	Optional pointer that receives the number of frames written to the output buffer.
[in]	mode	Bitwise OR of SceKernelBacktraceMode values.

Returns: With SCE_KERNEL_BACKTRACE_MODE_DONT_EXCEED, 0 on success. Otherwise, the complete call-stack depth on success, even when the output buffer is too small to contain every frame. Returns < 0 on error.

◆ sceKernelGetTimerInfo()

int sceKernelGetTimerInfo	(	SceUID	timer_id,
		SceKernelTimerInfo *	info
	)

Gets timer information.

Parameters

[in]	timer_id	Timer identifier.
[in,out]	info	Must point to a SceKernelTimerInfo structure. Its first field, `size`, sets the exact number of bytes copied to and from the structure, up to the full 0x60-byte structure on FW 3.60.

Returns: 0 on success, or < 0 on error.

◆ sceKernelGetTimerTime()

int sceKernelGetTimerTime	(	SceUID	timer_id,
		SceKernelSysClock *	timer_time

Gets the current timer time.

Parameters

[in]	timer_id	Timer identifier.

Creates a PC activation challenge.

◆ sceKernelWaitEvent()

SceInt32 sceKernelWaitEvent	(	SceUID	event_id,
		SceUInt32	wait_pattern,
		SceUInt32 *	result_pattern,
		SceUInt64 *	user_data,
		SceUInt32 *	timeout
	)

Waits until any requested event bit is present.

When the event has the auto-clear attribute, the matched bits are removed after a successful wait. This function does not dispatch callbacks while blocked.

Parameters

[in]	event_id	Event identifier.
[in]	wait_pattern	Pattern of bits to wait for.
[out]	result_pattern	Optional pointer that receives the matched bits.
[out]	user_data	Optional pointer that receives the event's user data.
[in,out]	timeout	Optional timeout in microseconds. If the call blocks, it receives the remaining duration; it receives 0 when the timeout expires. It is left unchanged when the wait is satisfied immediately.

Returns: 0 on success, or < 0 on error.
