createThread 的问题

Question

我用DWORD WINAPI workThread(LPVOID lParam)定义了一个线程，可在createthread时提示无法将参数3从DWORD（LPVOID）转化为LPTHREAD_START_ROUTINE,郁闷，高不明白！！
我的createthread函数 为 hThread = CreateThread(NULL,0,workThread,&dwThrdParam,0,&threadID);
请给于指点！！

Answer 1

HANDLE CreateThread(
  LPSECURITY_ATTRIBUTES lpThreadAttributes,  // pointer to security attributes
  DWORD dwStackSize,                         // initial thread stack size
  LPTHREAD_START_ROUTINE lpStartAddress,     // pointer to thread function
  LPVOID lpParameter,                        // argument for new thread
  DWORD dwCreationFlags,                     // creation flags
  LPDWORD lpThreadId                         // pointer to receive thread ID
);
你的两个参数调错了
hThread = CreateThread(NULL,0,workThread,NULL,&dwThrdParam,&threadID);

Answer 2

把
hThread = CreateThread(NULL,0,workThread,&dwThrdParam,0,&threadID);
改为
hThread = CreateThread(NULL,0,
                      (LPTHREAD_START_ROUTINE)workThread,
                      &dwThrdParam,0,&threadID);就可以了。

Answer 3

不行的话可以强制转换试试hThread = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)workThread,&dwThrdParam,0,&threadID);

Answer 4

hThread = CreateThread(NULL,0,workThread,&dwThrdParam,0,&threadID);
没有问题，用LPTHREAD_START_ROUTINE强制转换
hThread = CreateThread(NULL,0,（LPTHREAD_START_ROUTINE ）workThread,&dwThrdParam,0,&threadID);

Answer 5

强制转换可以！
hThread = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)workThread,&dwThrdParam,0,&threadID);
