Answer 1

您的代码确实有效。只需要一点点改变:

HANDLE h = CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD, 0);
if (h != INVALID_HANDLE_VALUE)
{
    THREADENTRY32 te;
    te.dwSize = sizeof(te);
    if (Thread32First(h, &te))
    {
        do
        {
            //in THREADENTRY32 structure there is a member called th32OwnerProcessID
            //you can check owner process of thread like this:
            if (te.th32OwnerProcessID == 5454)
            {
                wprintf(L"Process %u IdThred=%u\n", te.th32OwnerProcessID, te.th32ThreadID);
            }
        } while (Thread32Next(h, &te));
    }
    CloseHandle(h);
}
