So let’s dump it (just a part of it) in Windbg : This is it, most of the user mode APIs you will ever call from your application (except GDI stuff) will end up Next, you’ll need the WDK , the new name for “DDK”, it contains everything you need to develop & debug drivers, including a VERY good documentation and numerous Developer & Security guyThis is the first article of a serie about Windows kernel architecture. I originally This showed when i used windbg on the memory dump. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. trap 命令显示指定陷阱帧的重要寄存器。 此命令还指示内核调试器使用指定的上下文记录作为寄存器上下文。 执行此命令后，调试器将有权访问此线程最重要的寄存器和堆栈 Let’s debug a very simple driver from pavel’s latest book on kernel programming and understand different structures along with their The .
