DEVPROPKEY structure

  • Article

In Windows Vista and later versions of Windows, the DEVPROPKEY structure represents a device property key for a device property in the unified device property model.

Syntax

struct DEVPROPKEY {
  DEVPROPGUID fmtid;
  DEVPROPID   pid;
};

Members

fmtid
A DEVPROPGUID-typed value that specifies a property category.

The DEVPROPGUID data type is defined as:

typedef GUID  DEVPROPGUID, *PDEVPROPGUID;

pid
A DEVPROPID-typed value that uniquely identifies the property within the property category. For internal system reasons, a property identifier must be greater than or equal to two.

The DEVPROPID data type is defined as:

typedef ULONG DEVPROPID, *PDEVPROPID;

Remarks

The DEVPROPKEY structure is part of the unified device property model.

The basic set of system-supplied device property keys are defined in Devpkey.h.

The DEFINE_DEVPROPKEY macro creates an instance of a DEVPROPKEY structure that represents a device property key.

Requirements

Header

 Devpropdef.h (include Devpropdef.h)
