Deviceiocontrol kernel driver

i have a driver that works in kernel mode .sys) with IOCONTROL function in it. i created a www.doorway.ru that calls the driver using the DeviceIOcontrol function in order to do that. the problem is that after i created www.doorway.ru .sys and tried to debug, (with VC 6) i got this announcments: loaded `www.doorway.ru`, no matching symbolic information found.5/5.  · But i don't know how to send app data to driver. DeviceIoControl's 3, 4 parameters are input buffer and length. If I add char InputBuffer[] = "InputBuffer's data"; in app, how driver can receive this data? I want to use DbgPrint() for accepted data from www.doorway.rus: 8.  · "The DeviceIoControl function provides a device input and output control (IOCTL) interface through which an application can communicate directly with a device driver." But How do i receive LPVOID lpInBuffer, DWORD nInBufferSize, LPVOID lpOutBuffer, DWORD nOutBufferSize,Reviews: 1.

The kernel driver queues the event that occurred, and the user mode application issues the IOCTL to retrieve the contents of the queue. In this type of logic, the user-mode application will While execute the same loop as DeviceIoControl and will continue to communicate with the driver by calling. ZwDeviceIoControlFile provides a consistent view of the input and output data to the system and to kernel-mode drivers, while providing applications and underlying drivers with a device-dependent method of specifying a communications interface. "The DeviceIoControl function provides a device input and output control (IOCTL) interface through which an application can communicate directly with a device driver." But How do i receive LPVOID lpInBuffer, DWORD nInBufferSize, LPVOID lpOutBuffer, DWORD nOutBufferSize.

DeviceIoControl is one way of interacting with the driver, and other ways include ReadFile and WriteFile. In order for a driver to receive. Posts about Kernel written by Pavel Yosifovich. Dealing with user space buffers; Handling DeviceIoControl calls; Testing the driver. Buffered IO methods or named file mapping objects can be used; however, for simple device drivers the standard DeviceIoControl METHOD_ accesses are sufficient.
