INTERFACE_TYPE enumeration (wdm.h)

The INTERFACE_TYPE enumeration indicates the bus type.

Syntax

typedef enum _INTERFACE_TYPE {
  InterfaceTypeUndefined,
  Internal,
  Isa,
  Eisa,
  MicroChannel,
  TurboChannel,
  PCIBus,
  VMEBus,
  NuBus,
  PCMCIABus,
  CBus,
  MPIBus,
  MPSABus,
  ProcessorInternal,
  InternalPowerBus,
  PNPISABus,
  PNPBus,
  Vmcs,
  ACPIBus,
  MaximumInterfaceType
} INTERFACE_TYPE, *PINTERFACE_TYPE;

Constants

InterfaceTypeUndefined Indicates that the interface type is undefined.
Internal For internal use only.
Isa Indicates that the interface is published by the ISA bus driver.
Eisa Indicates that the interface is published by the EISA bus driver.
MicroChannel Indicates that the interface is published by the MicroChannel bus driver.
TurboChannel Indicates that the interface is published by the TurboChannel bus driver.
PCIBus Indicates that the interface is published by the PCI bus driver.
VMEBus Indicates that the interface is published by the VME bus driver.
NuBus Indicates that the interface is published by the NuBus driver.
PCMCIABus Indicates that the interface is published by the PCMCIA bus driver.
CBus Indicates that the interface is published by the Cbus driver.
MPIBus Indicates that the interface is published by the MPI bus driver.
MPSABus Indicates that the interface is published by the MPSA bus driver.
ProcessorInternal Indicates that the interface is published by the ISA bus driver.
InternalPowerBus Indicates that the interface is published for an internal power bus. Some devices have power control ports that allow them to share power control with other devices. The Windows architecture represents these devices as slots on a virtual bus called an "internal power bus."
PNPISABus Indicates that the interface is published by the PNPISA bus driver.
PNPBus Indicates that the interface is published by the PNP bus driver.
Vmcs Reserved for use by the operating system.
ACPIBus Indicates that the interface is published by the ACPI bus driver. The ACPI bus driver enumerates devices that are described in the ACPI firmware of the hardware platform. These devices might physically reside on buses that are controlled by other bus drivers, but the ACPI bus driver must enumerate these devices because the other bus drivers cannot detect them. This interface type is defined starting with Windows 8.
MaximumInterfaceType Marks the upper limit of the possible bus types.
