IOCTL_MINIPORT_PROCESS_SERVICE_IRP IOCTL

Description

This IOCTL is used by a user-mode application or kernel-mode driver that requires notification when something of interest happens in the virtual miniport. This IOCTL might be used, for example, when a vendor-specific, time-consuming operation such as device discovery completes.

Parameters

Major code

Input buffer

The buffer at Irp->AssociatedIrp.SystemBuffer contains a user-defined structure.

Input buffer length

Parameters.DeviceIoControl.InputBufferLength indicates the size, in bytes, of all the input data.

Output buffer

Updated user-defined structures are returned in the buffer at Irp->AssociatedIrp.SystemBuffer.

Output buffer length

The length of the buffer.

Input/output buffer
