Data Structure Documentation

SceBacktraceArgs

struct SceBacktraceArgs

Data Fields
SceUInt32 *	num_frames	Receives the number of frames written to the output buffer. May be NULL.
SceInt32	mode	Bitwise OR of SceKernelBacktraceMode values.
SceUInt32	reserved[2]	Copied from user memory but unused on FW 3.60.

Function Documentation

VITASDK_BUILD_ASSERT_EQ()

VITASDK_BUILD_ASSERT_EQ	(	0x10	,
		SceBacktraceArgs
	)

_sceKernelBacktrace()

SceInt32 _sceKernelBacktrace	(	SceUID	thread_id,
		SceKernelCallFrame *	call_frame_buffer,
		SceSize	num_bytes_buffer,
		const SceBacktraceArgs *	args
	)

Get a thread backtrace.

Parameters

[in]	thread_id	Thread ID, or SCE_KERNEL_BACKTRACE_CONTEXT_CURRENT.
[out]	call_frame_buffer	Buffer that receives 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 have room for at least one frame.
[in]	args	Backtrace parameters. Must be non-NULL.

Returns

On success, 0 with SCE_KERNEL_BACKTRACE_MODE_DONT_EXCEED set; otherwise, the total number of frames in the call stack, including frames that did not fit in the output buffer. Returns < 0 on error.

Note

On FW 3.60 this function requires development mode. Kernel-mode unwinding also requires the corresponding QAF permission.

Variable Documentation

num_frames

SceUInt32* SceBacktraceArgs::num_frames

mode

SceInt32 SceBacktraceArgs::mode

Bitwise OR of SceKernelBacktraceMode values.

reserved

SceUInt32 SceBacktraceArgs::reserved[2]

Copied from user memory but unused on FW 3.60.
