Used to indicate whether an interrupt was actually handled. If the processing routine finds that its device does need to be processed, it should return irq_handled. Otherwise.

A VxD handles interrupts in connection with Windows and performs I/O operations for applications that require I/O operations and does not affect the execution of other applications. Most VXD management hardware devices, there are also some VxD to manage or replace related software, such as the normal ROM BIOS. A VxD can contain device-related code that must be executed on the appropriate device, or it can rely on other

Taxi drivers give me an MBA From http://blog.csdn.net/psyl/archive/2006/03/17/627496.aspx I was about to rush to the airport from Xujiahui, so I ended a meeting in a hurry and searched for a taxi in front of the mercury building. A mass found me and was very professional and straight forward to me. This stops, so I am deeply shocked by the story that follows, like a vivid MBA Case Study. To be loyal to the original intention of the taxi driver, I trie

An MBA for taxi drivers One day, I rushed to the airport from Xujiahui and searched for a taxi in front of the mercury building. A "public" found me and ended up in front of me very professionally and directly. This pause gave me a story that shocked me deeply, like a vivid MBA Case Study."Where to go ...... Okay, airport. I like to do the business of the Miluo building in Xujiahui. Here I only do two places: the Miluo building and the Junyao building

Linux is a variant of the UNIX operating system, and the principle and idea of writing a driver in Linux is similar to that of other Unix systems, but it is very different for drivers in DOS or window environments. Design the driver in the Linux environment, the thought is concise, the operation is convenient, the function is also very formidable, but the support function is few, can only depend on the function in the kernel, some commonly used operat

ZZ: http://www.cnblogs.com/lzjsky/archive/2010/11/19/1881911.html In different scenarios, many driver writers need to share the memory between the driver and the user program. The two easiest technologies are: 1. The application sends IOCTL to the driver and provides a pointer to the memory. Then the driver and application can share the memory. (Application allocates shared memory)2. The driver allocates memory pages, maps these memory pages to the address space of the specified user mode proces
