关于THREADINFO结构的 有高手没啊

[danielwmm]

线程为窗口维护一个threadinfo结构，
threadinfo数据结构：
------------------
|登记消息队列指针|
------------------
|虚拟输入队列指针|
------------------
|发送消息队列指针|
------------------
|应答消息队列指针|
------------------
| nExitCode |
------------------
| 唤醒标志 |
------------------
|局部输入状态变量|
------------------

请问上面4个指针分别的作用是什么??举实例更好!谢谢大家啊!

我也找了的
没有,呵呵!

threadinfo怎么MSDN里没找到他?

是自己定义的吧?

有的，如下：
typedef struct tagTHREADINFO {
W32THREAD;

//***************************************** begin: USER specific fields

PTL ptlOb; // Listhead for kernel object thread lock list

int cEnterCount;

struct tagPROCESSINFO *ppi; // process info struct for this thread

struct tagQ *pq; // keyboard and mouse input queue

PKL spklActive; // active keyboard layout for this thread
MLIST mlPost; // posted message list.
USHORT fsChangeBitsRemoved;// Bits removed during PeekMessage

DWORD idLast;

int cQuit;
int exitCode;

int cPaintsReady;
UINT cTimersReady;

PMENUSTATE pMenuState;

union {

这个是未文档化的，当然在MSDN找补到
