RtlCaptureStackBackTrace

The RtlCaptureStackBackTrace routine captures a stack back trace by walking up the stack and recording the information for each frame.

USHORT
RtlCaptureStackBackTrace(
__in ULONG FramesToSkip,
__in ULONG FramesToCapture,
__out_ecount(FramesToCapture) PVOID *BackTrace,
__out_opt PULONG BackTraceHash
);

Parameters

FramesToSkip

The number of frames to skip from the start of the back trace.

FramesToCapture

The number of frames to be captured.

BackTrace

An array of pointers captured from the current stack trace.

BackTraceHash

An optional value that can be used to organize hash tables. If this parameter is NULL, no hash value is computed.

This value is calculated based on the values of the pointers returned in the BackTrace array. Two identical stack traces will generate identical hash values.

Return Value

The number of captured frames.

Comments

The RtlCaptureStackBackTrace routine captures a stack back trace by walking up the stack and recording the information for each frame.

Important This is an exported function that MUST probe the ability to take page faults.

In Windows XP and Windows Server 2003, the sum of the FramesToSkip and FramesToCapture parameters must be less than 63.

Requirements

Versions: Available in Windows XP and later versions of the Windows operating systems.

IRQL: <= DISPATCH_LEVEL

Headers: Declared in Ntifs.h. Include Ntifs.h or FltKernel.h.

Library: Contained in Ntoskrnl.lib.

The RtlCaptureStackBackTrace routine captures a stack trace by walking the stack and recording the information for each frame.

Syntax

C++Copy

 

NTSYSAPI USHORT RtlCaptureStackBackTrace(
  [in]            ULONG  FramesToSkip,
  [in]            ULONG  FramesToCapture,
  [out]           PVOID  *BackTrace,
  [out, optional] PULONG BackTraceHash
);

Parameters

[in] FramesToSkip

Number of frames to skip from the start (current call point) of the back trace.

[in] FramesToCapture

Number of frames to be captured.

[out] BackTrace

Caller-allocated array in which pointers to the return addresses captured from the current stack trace are returned.

[out, optional] BackTraceHash

Optional value that can be used to organize hash tables. If this parameter is NULL, RtlCaptureStackBackTrace does not compute and return a hash value.

This hash value is calculated based on the values of the pointers returned in the BackTrace array. Two identical stack traces will generate identical hash values.

Return value

The number of captured frames.

Remarks

RtlCaptureStackBackTrace captures a stack trace for the caller by walking the stack (walking back in call time), and recording information for each frame. Specifically, RtlCaptureStackBackTrace returns pointers to the return addresses of each call on the stack, where the first pointer in the BackTrace array points to the return address of the most recent call, and so on.

Back trace hash values can be used to quickly determine whether two stack traces are identical or different. You can use the hash returned in BackTraceHash to compare stack traces. If you don't want to use hashes, or want to compute your own hash values, set BackTraceHash to NULL.

Requirements

Library	NtosKrnl.lib; OneCoreUAP.lib on Windows 10
