???WINBASEAPI?HANDLE?WINAPI?CreateThread(LPSECURITY_ATTRIBUTES,DWORD,LPTHREAD_START_ROUTINE,PVOID,DWORD,PDWORD);
22
?????第一個(gè)參數(shù)是指向SECURITY_ATTRIBUTES型態(tài)的結(jié)構(gòu)的指針。在Windows?98中忽略該參數(shù)。在Windows?NT中，它被設(shè)為NULL。
23
??第二個(gè)參數(shù)是用于新線程的初始堆棧大小，默認(rèn)值為0。在任何情況下，Windows根據(jù)需要?jiǎng)討B(tài)延長(zhǎng)堆棧的大小。
24
?????第三個(gè)參數(shù)是指向線程函數(shù)的指標(biāo)。函數(shù)名稱沒(méi)有限制，但是必須以下列形式聲明:DWORD?WINAPI?ThreadProc?(PVOID?pParam)?;
25
?????第四個(gè)參數(shù)為傳遞給ThreadProc的參數(shù)。這樣主線程和從屬線程就可以共享數(shù)據(jù)。
26
?????第五個(gè)參數(shù)通常為0，但當(dāng)建立的線程不馬上執(zhí)行時(shí)為旗標(biāo)
27
?????第六個(gè)參數(shù)是一個(gè)指針，指向接受執(zhí)行緒ID值的變量
