__declspec(thread) int nCount = 0;//线程局部变量
DWORD WINAPI threadProc(LPVOID * wparm)
{
int i = 0;
while (1)
{
if (i == 20) break;

}
void CtestThreadDlg::OnBnClickedButton14()
{
HANDLE handle = ::CreateThread(NULL, 0,
(LPTHREAD_START_ROUTINE)threadProc,this, 0,NULL);//函数类型转换
}将类的成员函数,作为线程的回调函数.代码如下:
class test
{
UINT m_nCount;
public:
UINT WINAPI threadProc(LPVOID * wparm);
}
UINT __stdcall test::threadProc(LPVOID * wparm)
{
int i = 0;
while (1)
{
if (i == 20) break;
Sleep(30);
m_nCount =i++;
CString str;
str.Format(_T("%d\n"), m_nCount);
TRACE(str);
}
return 0;
}
void test::OnBnClickedStart()
{
typedef UINT (__stdcall *stdProc)(LPVOID);
typedef UINT (__stdcall test::* ProcObject)(LPVOID);
ProcObject theProc = (ProcObject)&test::threadProc;
HANDLE handle = CreateThread(NULL, 0,
(LPTHREAD_START_ROUTINE)*(stdProc*)&theProc,this, 0,NULL);
