指定一个目标进程，怎样得到目标进程内所有的线程信息啊？

Question

指定一个目标进程，怎样得到目标进程内所有的线程信息啊？就是能够得到目标进程内所有线程的Id就好了，谢谢了

Answer 1

BOOL ProcessInformation(DWORD dwProcessID)
{
    HANDLE          hThreadSnap  = NULL;
    HANDLE          hThread      = NULL;
    THREADENTRY32   ThreadEntry32; 

__try
{
hThreadSnap = CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD, 0); 
     if(hThreadSnap == INVALID_HANDLE_VALUE) 
     {
printf("CreateToolhelp32Snapshot for thread Error: %d\n",GetLastError());
bResult = FALSE;
__leave;
}// OpenThread = (HANDLE(__stdcall *)(DWORD,BOOL,DWORD))GetProcAddress(GetModuleHandle("kernel32"),"OpenThread");
if(OpenThread == NULL)
{
printf("GetProcAddress for OpentThread Error: %d\n",GetLastError());
bResult = FALSE;
__leave;
}

ThreadEntry32.dwSize = sizeof(THREADENTRY32); 
    if(Thread32First(hThreadSnap, &ThreadEntry32)) 
{
printf("%-10s%-10s%-9s%15s\n\n","ThreadID","BasePrio","CreateTime","ProcessorTime");
            do 
{
     if(ThreadEntry32.th32OwnerProcessID != dwProcessID)
{
continue;
}
            printf("%-10d",ThreadEntry32.th32ThreadID); 
printf("%8d",ThreadEntry32.tpBasePri);
  
hThread = OpenThread(THREAD_ALL_ACCESS,FALSE,ThreadEntry32.th32ThreadID);
if(hThread == NULL)
{
bResult = FALSE;
continue; 
} if(!GetThreadTimes(hThread,&CreateTime,&ExitTime,&KernelTime,&UserTime))
{
    bResult = FALSE;
}
    else
{
    FileTimeToSystemTime(&CreateTime,&SystemTime);
    printf("    %.2d:%.2d:%.2d",(SystemTime.wHour+8)%24,SystemTime.wMinute,SystemTime.wSecond);
ProcessTime.dwHighDateTime = KernelTime.dwHighDateTime + UserTime.dwHighDateTime;
ProcessTime.dwLowDateTime  = KernelTime.dwLowDateTime  + UserTime.dwLowDateTime;
FileTimeToSystemTime(&ProcessTime,&SystemTime);
printf("  %.2d:%.2d:%.2d.%.4d  ",SystemTime.wHour,SystemTime.wMinute,SystemTime.wSecond,SystemTime.wMilliseconds);
} printf("\n");
}while (Thread32Next(hThreadSnap, &ThreadEntry32)); 

printf("\nThread:\t %d\n",dwThread);
} 
    else 
{
printf("Thread32First Error: %d\n",GetLastError());
bResult = FALSE;
__leave;
}
}
__finally
{
if(hThreadSnap != NULL)
{
CloseHandle (hThreadSnap); 
}
}
}
能够获取线程ID,优先级，创建时间，进程时间4个属性。程序最好在VC7下面编译。

Answer 2

HMODULE hKernel = NULL;
HANDLE hSnapshot = NULL;
THREADENTRY32 te32 = {0};
DWORD dwThrdCount = 0;hKernel = GetModuleHandle("KERNEL32.DLL");
if(hKernel) {
    createtoolhelp32snapshot = (CREATESNAPSHOT)GetProcAddress(
  hKernel, "CreateToolhelp32Snapshot");    thread32first = (THREADWALK)GetProcAddress(hKernel, "Thread32First");    thread32next = (THREADWALK)GetProcAddress(hKernel, "Thread32Next");
}if(!(thread32first && thread32next && createtoolhelp32snapshot))
return;
hSnapshot = createtoolhelp32snapshot(TH32CS_SNAPTHREAD, 0);
if(hSnapshot == (HANDLE)-1) return;te32.dwSize = sizeof(THREADENTRY32);
if(thread32first(hSnapshot, &te32)) {
   do {
      if(te32.th32OwnerProcessID==你想要枚舉線程的進程ID){
  te32.th32ThreadID //得到指定進程ID的線程ID值
   dwThrdCount++; //統計線程個數
       }    } while(thread32next(hSnapshot, &te32));
} else {
dwThrdCount = 0;
}CloseHandle(hSnapshot);

Answer 3

CreateToolhelp32Snapshot(
  DWORD dwFlags,       
  DWORD th32ProcessID  //在这里代入id
);

Answer 4

使用PSAPI可以得到线程的更多信息。

Answer 5

其实就是得到所有线程的句柄，然后看他的processid是不是你指出的进程，如果是就记录下来，然后就可以了
