Addfilter is a command-line application which adds and removes filter drivers for a given drive or volume. It is intended to demonstrate how to insert a filter driver into the driver stack of a device. The sample illustrates how to do this by using the SetupDi APIs. The sample works on both x86 and Alpha platforms. It has only been tested in a 32-Bit environment. Since Addfilter is not a driver, it does not deal with Plug and Play or Power Management.

The CD Audio sample allows some non-SCSI2 CD ROMs to support audio operations by intercepting the relevant audio ioctls and translating them into the command block(s) expected by the non-compliant cdroms. It supports Plug and Play and Power Management, and is 64-Bit compliant.

The flpydisk sample is a floppy driver that resides in the directory \\Ntddk\Src\Storage\Fdc\Flpydsk. It is similar to a class driver in that it sits a level above the floppy disk controller in the driver stack, and brokers communication between the application level and the low-level driver. The floppy driver takes commands from the application and then calls routines in the controller which will in turn perform the actual interaction with the device. The sample compiles in 64-Bit, but has not been tested in this environment. It is compatible with x86 and Alpha platforms.

只包括兩個(gè)核心文件sha1.cpp及sha1.h 計(jì)算數(shù)據(jù)的sha1摘要。簡單，好用。 由于Bit endian及l(fā)ittle endian的原因，有些計(jì)算sha1摘要的算法計(jì)算出來的結(jié)果與正確結(jié)果有差異。此源碼經(jīng)過測試，與RFC里列出的測試結(jié)果匹配。

The original NuLib has been ported to many different systems. Version 3.2.5 is functionally similar to v3.2.4, but the source code and documentation were cleaned up by Devin Reade, making it easier to build. NuLib2 is generally superior, but NuLib does have the advantage of running under 16-Bit MS-DOS and GS/OS.

This firmware translates a PS/2 mouse to a USB mouse. The translator firmware is entirely interrupt driven (with the exception of sending the data via USB to the host.) An interrupt is generated when the PS/2 start Bit is received, at which time the firmware will begin its receive routine. In addition to this interrupt, every 168ms a timer overflow interrupts the main program and implements one state of the mouse state machine. This state machine handles sending bytes to and translating bytes received from the PS/2 mouse automatically. All of this is done in the background while the main program runs in the foreground. The only operation that the main program implements is sending mouse data to the PC via USB.
