线程句柄作WaitForSingleObject的参数是什么意思？

#include <windows.h>
#include <iostream.h>

DWORD WINAPI Fun1Proc(LPVOID lpParameter);

int main()
{
HANDLE hThread1;
hThread1 = CreateThread(NULL, 0, Fun1Proc, NULL, 0, NULL);

WaitForSingleObject(hThread1, INFINITE);

int i;
for(i = 0; i < 100; i++)
{
cout << "main thread " << i + 1 << endl;
}

CloseHandle(hThread1);
return 0;
}

DWORD WINAPI Fun1Proc(LPVOID lpParameter)
{
int i;
for(i = 0; i < 100; i++)
{
cout << "thread one " << i + 1 << endl;
}

return 0;
}
