检索Win64异常表中的所有条目 [英] Retrieving all the entries in the Win64 exception table

问题描述

从 Win64异常堆栈遍历不显示条目的清晰理解，我希望能够从Win64异常表中检索所有条目-包括API调用 RtlAddFunctionTable 和 RtlInstallFunctionTableCallback 。

From some clearer understanding from Win64 exception stack walking not displaying entries, I would like to be able retrieve all the entries from the Win64 exception table - including any run-time additions by the API calls RtlAddFunctionTable and RtlInstallFunctionTableCallback.

Delphi是否可能？

Is this possible from Delphi?

RtlVirtualUnwind(UNW_FLAG_NHANDLER,
                   LImageBase,
                   LContext.Rip,
                   LRuntimeFunction,
                   LContext,
                   HandlerData,
                   EstablisherFrame,
                   NvContext);

HandlerData 指针包含 <有关异常表的em>特定于编译器/语言的信息 。如果从 System.pas 撤消一些详细信息，尤其是方法 _DelphiExceptionHandler 和 FindOnExceptionDescEntry ，可以找出每个条目的用途-详细信息与 System.pas中的 TExcScope 记录定义相对。

The HandlerData pointer contains compiler/language specific information about the exception table. If you reverse some details from System.pas, in particular the methods _DelphiExceptionHandler and FindOnExceptionDescEntry, it is possible to figure out what each entry is for - the details are against the TExcScope record definition in System.pas.
