Dump文件数据存储格式(六）

八、线程信息列表流(ThreadInfoListStream)

ThreadInfoListStream包含了线程状态信息，在ThreadListStream的后面就是ThreadInfoListStream了。

ThreadListStream如下：

0x720+0n3796=0x15F4

而ThreadInfoListStream如下：

所以ThreadInfoListStream紧挨着ThreadListStream，大小为5068字节。数据如下：

ThreadInfoListStream的数据由两个结构组成，一个是MINIDUMP_THREAD_INFO_LIST，另一个是MINIDUMP_THREAD_INFO。

MINIDUMP_THREAD_INFO_LIST包含数据大小的信息，相当于头部结构，如下：

typedef struct _MINIDUMP_THREAD_INFO_LIST {
  ULONG SizeOfHeader;
  ULONG SizeOfEntry;
  ULONG NumberOfEntries;
} MINIDUMP_THREAD_INFO_LIST, *PMINIDUMP_THREAD_INFO_LIST;

成员如下：

SizeOfHeader

流的头数据的大小，以字节为单位。这通常是sizeof（MINIDUMP_THREAD_INFO_LIST）。

SizeOfEntry

头后面的每个条目的大小（以字节为单位）。这通常是sizeof（MINIDUMP_THREAD_INFO）。

NumberOfEntries

流中的条目数。这些通常是MINIDUMP_THREAD_INFO结构。条目跟随头部。

根据以上信息，我们可以做如下计算：

12+64*79=5068，刚好等于流目录里的DataSize,如下:

而MINIDUMP_THREAD_INFO结构包含线程真实的状态信息，如下：

typedef struct _MINIDUMP_THREAD_INFO {
  ULONG32 ThreadId;
  ULONG32 DumpFlags;
  ULONG32 DumpError;
  ULONG32 ExitStatus;
  ULONG64 CreateTime;
  ULONG64 ExitTime;
  ULONG64 KernelTime;
  ULONG64 UserTime;
  ULONG64 StartAddress;
  ULONG64 Affinity;
} MINIDUMP_THREAD_INFO, *PMINIDUMP_THREAD_INFO;

成员如下：

ThreadId

线程标识

DumpFlags

指示线程状态的标志。此成员可以是0或以下值之一。

Members

Value	Meaning
MINIDUMP_THREAD_INFO_ERROR_THREAD 0x00000001	A placeholder thread due to an error accessing the thread. No thread information exists beyond the thread identifier.
MINIDUMP_THREAD_INFO_EXITED_THREAD 0x00000004	The thread has exited (not running any code) at the time of the dump.
MINIDUMP_THREAD_INFO_INVALID_CONTEXT 0x00000010	Thread context could not be retrieved.
MINIDUMP_THREAD_INFO_INVALID_INFO 0x00000008	Thread information could not be retrieved.
MINIDUMP_THREAD_INFO_INVALID_TEB 0x00000020	TEB information could not be retrieved.
MINIDUMP_THREAD_INFO_WRITING_THREAD 0x00000002	This is the thread that called MiniDumpWriteDump.

DumpError

一个指示转储状态HRESULT值 .

ExitStatus

线程退出状态码

CreateTime

线程创建的时间，从1601年1月1日（UTC）开始，以100纳秒为间隔。

ExitTime

线程退出的时间，从1601年1月1日（UTC）开始，以100纳秒为间隔。

KernelTime

在内核模式下执行的时间，以100纳秒为间隔。

UserTime

在用户模式下执行的时间，以100纳秒为间隔。

StartAddress

线程的起始地址。

Affinity

处理器关联掩码
