pThreadClass
The RUNTIME_CLASS of an object derived from CWinThread.
pParam
Parameter to be passed to the controlling function as shown in the parameter to the function declaration in pfnThreadProc.
nPriority
The desired priority of the thread. If 0, the same priority as the creating thread will be used. For a full list and description of the available priorities, see SetThreadPriority in the Platform SDK.
nStackSize
Specifies the size in bytes of the stack for the new thread. If 0, the stack size defaults to the same size stack as the creating thread.
dwCreateFlags
Specifies an additional flag that controls the creation of the thread. This flag can contain one of two values:
CREATE_SUSPENDED Start the thread with a suspend count of one. Use CREATE_SUSPENDED if you want to initialize any member data of the CWinThread object, such as m_bAutoDelete or any members of your derived class, before the thread starts running. Once your initialization is complete, use CWinThread::ResumeThread to start the thread running. The thread will not execute until CWinThread::ResumeThread is called.
0 Start the thread immediately after creation.
lpSecurityAttrs
Points to a SECURITY_ATTRIBUTES structure that specifies the security attributes for the thread. If NULL, the same security attributes as the creating thread will be used. For more information on this structure, see the Platform SDK.

);//用于創(chuàng)建工作者線程
返回值: 一個(gè)指向新線程的線程對(duì)象
pfnThreadProc : 線程的入口函數(shù),聲明一定要如下: UINT MyThreadFunction( LPVOID pParam );
pParam : 傳遞入線程的參數(shù),注意它的類型為:LPVOID,所以我們可以傳遞一個(gè)結(jié)構(gòu)體入線程.
nPriority : 線程的優(yōu)先級(jí),一般設(shè)置為 0 .讓它和主線程具有共同的優(yōu)先級(jí).
nStackSize : 指定新創(chuàng)建的線程的棧的大小.如果為 0,新創(chuàng)建的線程具有和主線程一樣的大小的棧
dwCreateFlags : 指定創(chuàng)建線程以后,線程有怎么樣的標(biāo)志.可以指定兩個(gè)值:
CREATE_SUSPENDED : 線程創(chuàng)建以后,會(huì)處于掛起狀態(tài),真到調(diào)用: ResumeThread
0 : 創(chuàng)建線程后就開始運(yùn)行.
