02/22/2024

An SP_DEVICE_INTERFACE_DATA structure defines a device interface in a device information set.

Syntax

typedef struct _SP_DEVICE_INTERFACE_DATA {
  DWORD     cbSize;
  GUID      InterfaceClassGuid;
  DWORD     Flags;
  ULONG_PTR Reserved;
} SP_DEVICE_INTERFACE_DATA, *PSP_DEVICE_INTERFACE_DATA;

Members

cbSize

The size, in bytes, of the SP_DEVICE_INTERFACE_DATA structure. For more information, see the Remarks section.

InterfaceClassGuid

The GUID for the class to which the device interface belongs.

Flags

Can be one or more of the following:

SPINT_ACTIVE

The interface is active (enabled).

SPINT_DEFAULT

The interface is the default interface for the device class.

SPINT_REMOVED

The interface is removed.

Reserved

Reserved. Do not use.

Remarks

A SetupAPI function that takes an instance of the SP_DEVICE_INTERFACE_DATA structure as a parameter verifies whether the cbSize member of the supplied structure is equal to the size, in bytes, of the structure. If the cbSize member is not set correctly, the function will fail and set an error code of ERROR_INVALID_USER_BUFFER.
