Device content As we all know, the device context is a Windows data structure that contains information about the drawing properties of a device, such as a display or printer. All painting calls are performed through the device context object, including the paint brush, bitmap, and painting brush. The

(void *start, size_t length);3. Virtual Memory Area:The virtual memory area is a homogeneous interval in the virtual address space of the process, that is, a contiguous address range with the same characteristics. The memory image of a process consists of the following parts: program code, data, BSS and stack areas, and memory-mapped regions.The Linux kernel uses the VM_AREA_STRUCT structure to describe the virtual memory area. Its main members:unsigned long vm_start; /* Our start address withi

Question one: Why the device tree is needed. In the current widely used Linux kernel 2.6.x version, for different platforms, different hardware, there is often a large number of different, poor portability of the board level Description code to achieve these different platforms and different hardware special adaptation Demand. But too many platforms and different hardware have led to more and more such code, such as Arch/arm/plat-xxx and arch/arm/mach

Method One: Release clear off the clipboard Caused "Unable to stop the universal volume device", generally there are reasons, such as the above mentioned reason is the most common, the solution can be released to clear off the Clipboard, you can casually copy anything on the hard drive to rele

DTS (device tree source)The. dts file is a description of the device tree in ASCII text format, which is very user-friendly and suitable for human reading habits. Basically, in Arm Linux, a. dts file corresponds to an arm of the machine, typically placed in the kernel's arch/arm/boot/dts/directory. Since an SOC may correspond to multiple machine (one SOC can correspond to multiple products and circuit board

Transferred from http://blog.csdn.net/yj4231/article/details/7799245 In this paper, a simple analysis of the SYSFS in Linux system, to analyze the SYSFS must analyze the kernel of the Driver-model (drive model), the two are closely related. In the analysis process, this article will take the platform bus and the SPI main controller's platform drive as an example to explain. In fact, the platform mechanism is based on Driver-model, through this article, will also have a simple understanding of th
