Deviceiocontrol driver example

When you make an asynchronous call to DeviceIoControl, the calling thread doesn t block immediately. Instead, it continues processing until it reaches the point where it requires the result of the control operation. At that point, it calls an API that will block the thread until the driver completes the operation. For example.  · "The DeviceIoControl function provides a device input and output control (IOCTL) interface through which an application can communicate directly with a device driver." But How do i receive LPVOID lpInBuffer, DWORD nInBufferSize, Reviews: 1.  · This sample shows how to access devices from UWP applications using familiar win32 APIs like CreateFile (), ReadFile (), WriteFile (), and DeviceIoControl (). Some reasons you may want to do this are: You have existing code that uses CreateFile ()/DeviceIoControl () You prefer the programming model of the win32 APIs to www.doorway.ru
