Driverentry windows 7

TDL designed only for x64 Windows, Vista not listed as supported because it is obsolete. Administrative privilege is required. No SEH support for target drivers. No driver unloading. Only ntoskrnl import resolved, everything else is up to you. Dummy driver examples provided. You use it at your own risk.

Some lazy AV may flag this loader as malware. TDL does not patch any kernel variables, which makes it friendly to PatchGuard. It uses small shellcode which maps your driver to kernel mode without involving Windows loader and as result without triggering any parts of DSE and executes it. Privacy policy. DriverEntry is the first driver-supplied routine that is called after a driver is loaded.

It is responsible for initializing the driver. Otherwise, it must return one of the error status values that are defined in ntstatus. Like all WDM drivers, framework-based drivers must have a DriverEntry routine, which is called after the driver is loaded. A framework-based driver's DriverEntry routine must:. Activate WPP software tracing. When the system calls your driver's DriverEntry routine, it passes the driver a path to the driver's key in the appropriate Services tree.

Your driver must pass this path to WdfDriverCreate. A driver's software key is also called its driver key. The system stores information about each driver under its software key. When a driver stack informs the Plug and Play PnP manager that a device is connected to the system, the PnP manager creates a hardware key for the device. This key is also called a device key.

The DDK-supplied build tools automatically inform the linker that the driver's entry point is called DriverEntry , so giving the routine another name requires you to modify the build tools.

For more information about build tools, see Building a Driver. To define a DriverEntry callback routine, you must first provide a function declaration that identifies the type of callback routine you're defining. Windows provides a set of callback function types for drivers. Declaring a function using the callback function types helps Code Analysis for Drivers , Static Driver Verifier SDV , and other verification tools find errors, and it's a requirement for writing drivers for the Windows operating system.
