windows多线程编程_python的优点_windows多线程编程实例(5)

hThread = _beginthread (ThreadProc, uiStackSize, pParam) ;

它更简单，对于大多数应用程序很完美，这个线程函数的语法为：

void __cdecl ThreadProc (void * pParam) ;

在建立多线程的Windows程序时，需要在「Project Settings」对话框中做一些修改。选择「C/C」页面标签，然后在「Category」下拉式清单方块中选择「Code Generation」。在「Use Run-Time Library」下拉式清单方块中，可以看到用于「Release」设定的「Single-Threaded」和用于Debug设定的「Debug Single-Threaded」。将这些分别改为「Multithreaded」和「Debug Multithreaded」。这将把编译器旗标改为/MT，它是编译器在编译多线程的应用程序所需要的。
