读写器
在计算机科学中，读者作家问题是并发中常见的计算问题的例子。有至少三种变体的问题，处理多个线程试图同时访问同一共享的内存的情况。某些线程可以读，有的会写，约束没有进程可以访问为读取或写入，而另一个进程共享处于向其中写入信息的行为。（尤其是，它被允许两个或更多的读者，在同一时间访问该共享。读者-编写器锁是一种数据结构，解决了一个或多个读者作家问题。

si.wShowWindow = SW_SHOW;
si.dwFlags = STARTF_USESHOWWINDOW;
TCHAR szPath[] = TEXT("c:windowssystem32

BOOL bRet = ::CreateProcess(NULL, szPath, NULL, FALSE, NULL, NULL, NULL, NULL, &si, &pi);
int error = GetLastError();
if (bRet)

Display a Web Page in a Plain C Win32 Application:
There are numerous examples that demonstrate how to embed Internet Explorer in your own window. But these examples typically use Microsoft Foundation Classes (MFC), .NET, C#, or at least the Windows Template Library (WTL) because those frameworks have pre-fabricated "wrappers" to easily give you an "HTML control" to embed in your window. If you re trying to use plain C, without MFC, WTL, .NET, C#, or even any C++ code at all, then there is a dirth of examples and information how to deal with OLE/COM objects such as IE s IWebBrowser2. Here is an article and working example in C to specifically show you what you need to do in order to embed IE in your own window, and more generally, show you how to interact with OLE/COM objects and create your own objects in plain C.
