Field Documentation

UNICODE_STRING _ARCH_DEVICE_EXTENSION::DeviceName

The name of this device Definition at line 65 of file arch_cbm_driver.h.

BOOLEAN _ARCH_DEVICE_EXTENSION::DoNotReleaseBus

FLAG: We are not allowed to release and init the bus on initialization or deinitialization, because a TALK without a corresponding UNTALK has been issued. Definition at line 107 of file arch_cbm_driver.h.

KEVENT _ARCH_DEVICE_EXTENSION::EventWaitForListener

This even is used to wake-up the task inside of wait_for_listener() again Definition at line 87 of file arch_cbm_driver.h.

PDEVICE_OBJECT _ARCH_DEVICE_EXTENSION::Fdo

Pointer to the functional device object Definition at line 48 of file arch_cbm_driver.h.

ULONG _ARCH_DEVICE_EXTENSION::HandleEcpEppMyself

!= 0 if ECP/EPP modes are not handled by parport.sys, but by us. This is only allowed if we are running on NT4. Remarks: The NT4 code uses this internally to remember the type of parallel port (ECP, EPP, SPP, bidir). Definition at line 58 of file arch_cbm_driver.h.

KIRQL _ARCH_DEVICE_EXTENSION::IecBlockIrqPreviousIrql

Helper for cbmiec_block_irq Definition at line 119 of file arch_cbm_driver.h.

QUEUE _ARCH_DEVICE_EXTENSION::IrpQueue

QUEUE structure which allows us queueing our IRPs Definition at line 68 of file arch_cbm_driver.h.

BOOLEAN _ARCH_DEVICE_EXTENSION::IsNT4

Are we running on an NT4 system? Definition at line 51 of file arch_cbm_driver.h.

BOOLEAN _ARCH_DEVICE_EXTENSION::ParallelPortAllocated

FLAG: We already allocated the parallel port Definition at line 96 of file arch_cbm_driver.h.

BOOLEAN _ARCH_DEVICE_EXTENSION::ParallelPortAllocatedInterrupt

FLAG: The interrupt for the parallel port has been allocated Definition at line 102 of file arch_cbm_driver.h.

PDEVICE_OBJECT _ARCH_DEVICE_EXTENSION::ParallelPortFdo

The DEVICE_OBJECT of the parallel port driver Definition at line 74 of file arch_cbm_driver.h.

PFILE_OBJECT _ARCH_DEVICE_EXTENSION::ParallelPortFileObject

The FILE_OBJECT of the parallel port driver Definition at line 71 of file arch_cbm_driver.h.

BOOLEAN _ARCH_DEVICE_EXTENSION::ParallelPortIsLocked

FLAG: Is the parallel port currently locked? Definition at line 90 of file arch_cbm_driver.h.

BOOLEAN _ARCH_DEVICE_EXTENSION::ParallelPortLock

FLAG: Lock the parallel port, regardless if the driver is uninstalled. Definition at line 93 of file arch_cbm_driver.h.

BOOLEAN _ARCH_DEVICE_EXTENSION::ParallelPortModeSet

FLAG: The mode of the parallel port has already been set Definition at line 99 of file arch_cbm_driver.h.

PARALLEL_INTERRUPT_INFORMATION _ARCH_DEVICE_EXTENSION::Pii

Return value after connection the ISR Definition at line 83 of file arch_cbm_driver.h.

PARALLEL_INTERRUPT_SERVICE_ROUTINE _ARCH_DEVICE_EXTENSION::Pisr

Info for the ISR routine Definition at line 80 of file arch_cbm_driver.h.

PPARALLEL_PORT_INFORMATION _ARCH_DEVICE_EXTENSION::PortInfo

Information about the port we are connected to Definition at line 77 of file arch_cbm_driver.h.

BOOLEAN _ARCH_DEVICE_EXTENSION::QuitThread

Boolean value: Should the running thread quit itself? Definition at line 116 of file arch_cbm_driver.h.

PKTHREAD _ARCH_DEVICE_EXTENSION::Thread

Pointer to the thread structure Definition at line 113 of file arch_cbm_driver.h.

HANDLE _ARCH_DEVICE_EXTENSION::ThreadHandle

The thread handle for the worker thread Definition at line 110 of file arch_cbm_driver.h.
