如何在 Windows 性能分析器中命名线程

Question

我试图在Windows Performance Analyzer（WPA）（在Windows 8.1下）中显示线程的名称。此工具有一个名为"线程名称"的列。

我关注了著名的MSDN文章：

http://msdn.microsoft.com/en-US/library/xcb2z8hs（v=vs.110）.aspx

但是，看起来它在 WPA 中不起作用。根据第三方文档，只有Microsoft的Visual Studio和WinDbg调试器支持此异常。

那么如何命名线程，使其名称可以在 WPA 中显示呢？

Answer 1

> 从 Windows 10 版本 1607 开始，您可以使用 SetThreadDescription（） API，现在在 xperf/WPA 中受支持：

您还可以在此处投票支持将其添加到其他Microsoft工具中：

Answer 2

没有方便地安装 wpa，所以无法回答您的查询，但谢谢我从来没有想过这也可以使用本机代码的问题可以派上用场

#include <windows.h>
#include <stdio.h>
const DWORD MS_VC_EXCEPTION=0x406D1388;
//EmptyBlock,Constant in__except() and lpparam not used in ThreadProc
#pragma warning( disable : 6312 6322 4100 ) 
#pragma pack(push,8)
typedef struct tagTHREADNAME_INFO {
    DWORD dwType; // Must be 0x1000.
    LPCSTR szName; // Pointer to name (in user addr space).
    DWORD dwThreadID; // Thread ID (-1=caller thread).
    DWORD dwFlags; // Reserved for future use, must be zero.
} THREADNAME_INFO;
#pragma pack(pop)
DWORD WINAPI ThreadProc( LPVOID lpParam ) {
    int ch = 0; while(ch != 'y') { ch = getchar(); } return 0;}
void SetThreadName( DWORD dwThreadID, char* threadName) {
    THREADNAME_INFO info; info.dwType = 0x1000; info.szName = threadName;
    info.dwThreadID = dwThreadID; info.dwFlags = 0;
    __try {
        RaiseException( MS_VC_EXCEPTION, 0,
            sizeof(info)/sizeof(ULONG_PTR), (ULONG_PTR*)&info );
    }
    __except( EXCEPTION_CONTINUE_EXECUTION) {    }
}
void main (void) {
    HANDLE hThread = NULL;
    printf("nnn=======Creating Thread And Naming It================nnn");
    if (( hThread = CreateThread(NULL,NULL,ThreadProc,NULL,NULL,NULL)) != NULL) {
        SetThreadName(GetCurrentThreadId(), "nnMy New Shiny Threadnn");
        WaitForSingleObject(hThread,INFINITE);
        printf("Named Thread Terminated Main is terminatingn");
        CloseHandle(hThread);
    }
}

编译的链接和风袋 VCPP 事件似乎在 windBG 中处理此异常想知道 MAGIC Dword dbce 处理什么
