-description

The IOCTL_INTERNAL_GET_MORE_PARALLEL_PORT_INFO request returns information about a parallel port. This information supplements the information that a client obtains by using an IOCTL_INTERNAL_GET_PARALLEL_PORT_INFO request. The additional information about the parallel port includes the type of system interface, the bus number, and the interrupt resources used by the port.

For more information, see Obtaining Information About a ParallelPort.

IRP_MJ_INTERNAL_DEVICE_CONTROL

-input-buffer

A MORE_PARALLEL_PORT_INFORMATION structure.

-input-buffer-length

The Parameters.DeviceIoControl.OutputBufferLength member is set to the size, in bytes, of a MORE_PARALLEL_PORT_INFORMATION structure.

-output-buffer

The AssociatedIrp.SystemBuffer member points to a MORE_PARALLEL_PORT_INFORMATION structure that the client allocates to output parallel port information.

-output-buffer-length

The size of a MORE_PARALLEL_PORT_INFORMATION structure.

-in-out-buffer

-inout-buffer-length

-status-block

If the request succeeds, the Information member is set to the size, in bytes, of the MORE_PARALLEL_PORT_INFORMATION structure. Otherwise; the Information member is set to zero.

The Status member is set to one of the generic status values returned by internal device control requests for parallel ports or to the following value:

STATUS_BUFFER_TOO_SMALL

The value of the Parameters.DeviceIoControl.OutputBufferLength member is less than the size, in bytes, of a MORE_PARALLEL_PORT_INFORMATION structure.
