win32API多线程编程

win32线程API 在Windows平台下可以通过Windows的线程库来实现多线程编程。 对于多线程程序可以使用Visual Studio调试工具进行调试,也可以使用多核芯片厂家的线程分析调试工具进行调试。 Win32 API(了解Windows,代码小,效率高) Windows操作系统为内核以及应用程序之间提供的接口 将内核提供的功能进行函数封装 应用程序通过调用相关的函数获得相应的系统功能 _beginthread _beginthread(函数名,栈大小,参数指针) Win32 函数库中提供了操作多线程的函数, 包括创建线程、管理线程、终止线程、线程同步等接口。 线程函数(线程开始执行的函数) DWORD WINAPI ThreadFunc (LPVOID lpvThreadParm ); 线程创建 HANDLE CreateThread ( LPSECURITY_ATTRIBUTES lpThreadAttributes, SIZE_T dwStackSize, LPTHREAD_START_ROUTINE lpStartAddress, LPVOID lpParameter, DWORD dwCreationFlags, LPDWORD lpThreadId ); 第一个参数lpThreadAtt,是一个指向SECURITY- ATTRIBUTES结构的指针

problems using CreateThread on a member function

问题 I am trying to create a thread in an object, however I get an error saying '&' : illegal operation on bound member function expression. Reading up I saw I have to make the member function static, but when I do that I get an error saying left of '.dac_ping' must have class/struct/union this is what I am trying: class Dac { private: network_com com; HANDLE ping_thread; DWORD dping_thread; static DWORD WINAPI ping_loop(void* param) { while ( com.dac_ping() == 0) Sleep(900); return 1; //since

WindowsAPI - CreateThread的说明

我们两清 提交于 2019-11-29 10:02:49
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 ); 第一个参数是指向SECURITY_ATTRIBUTES型态的结构的指针。在Windows 98中忽略该参数。在Windows NT中,它被设为NULL。第二个参数是用于新线程的初始堆栈大小,默认值为0。在任何情况下,Windows根据需要动态延长堆栈的大小。 CreateThread的第三个参数是指向线程函数的指标。函数名称没有限制,但是必须以下列形式声明: DWORD WINAPI ThreadProc (PVOID pParam) ;

开始本应该是一篇洋洋洒洒的文字, 不过我还是提倡先做起来, 在尝试中去理解. 先试试这个: procedure TForm1.Button1Click(Sender: TObject); var i: Integer; begin for i := 0 to 500000 do begin Canvas.TextOut(10, 10, IntToStr(i)); end; end; View Code 上面程序运行时, 我们的窗体基本是 "死" 的, 可以在你在程序运行期间拖动窗体试试... Delphi 为我们提供了一个简单的办法(Application.ProcessMessages)来解决这个问题: procedure TForm1.Button1Click(Sender: TObject); var i: Integer; begin for i := 0 to 500000 do begin Canvas.TextOut(10, 10, IntToStr(i)); Application.ProcessMessages; end; end; View Code 这个 Application.ProcessMessages; 一般用在比较费时的循环中, 它会检查并先处理消息队列中的其他消息. 但这算不上多线程, 譬如: 运行中你拖动窗体, 循环会暂停下来...
