Typedef Documentation

StackFrameCallback

typedef Status(* StackFrameCallback) (const _tagSTACKFRAME64 *frame, uintptr_t cbData)

called for each stack frame found by wdbg_sym_WalkStack.

Parameters

frame	the dbghelp stack frame (we can't just pass the instruction-pointer because dump_frame_cb needs the frame pointer to locate frame-relative variables)
cbData	the user-specified value that was passed to wdbg_sym_WalkStack

Returns

Status (see RETURN_STATUS_FROM_CALLBACK).

Function Documentation

wdbg_sym_WalkStack()

Status wdbg_sym_WalkStack	(	StackFrameCallback	cb,
		uintptr_t	cbData,
		CONTEXT &	context,
		const wchar_t *	lastFuncToSkip = 0
	)

Iterate over a call stack, invoking a callback for each frame encountered.

Parameters

cb
cbData
context	Processor context from which to start (taken from an exception record or debug_CaptureContext).
lastFuncToSkip

Note

It is safe to use ENSURE/debug_warn/WARN_RETURN_STATUS_IF_ERR even during a stack trace (which is triggered by ENSURE et al. in app code) because nested stack traces are ignored and only the error is displayed.
