SetupDiSetClassProperty function

The SetupDiSetClassProperty function sets a class property for a device setup class or a device interface class.

Syntax


BOOL SetupDiSetClassProperty(
  _In_      const GUID *ClassGuid,
  _In_      const DEVPROPKEY *PropertyKey,
  _In_      DEVPROPTYPE PropertyType,
  _In_opt_  const PBYTE PropertyBuffer,
  _In_      DWORD PropertyBufferSize,
  _In_      DWORD Flags
);

Parameters

ClassGuid [in]

A pointer to a GUID that identifies the device setup class or device interface class for which to set a device property. For information about how to specify the class type, see the Flags parameter.

PropertyKey [in]

A pointer to a DEVPROPKEY structure that represents the device property key of the device class property to set.

PropertyType [in]

A DEVPROPTYPE-typed value that represents the property-data-type identifier for the device class property. For more information about the property-data-type identifier, see the Remarks section later in this topic.

PropertyBuffer [in, optional]

A pointer to a buffer that contains the property value of the device class. If either the property or the data is being deleted, this pointer must be set to NULL, and PropertyBufferSize must be set to zero. For more information about property data, see the Remarks section later in this topic.

PropertyBufferSize [in]

The size, in bytes, of the PropertyBuffer buffer. If PropertyBuffer is set to NULL, PropertyBufferSize must be set to zero.

Flags [in]

One of the following values, which specifies whether the class is a device setup class or a device interface class:

DICLASSPROP_INSTALLER

ClassGuid specifies a device setup class. This flag cannot be used with DICLASSPROP_INTERFACE.

DICLASSPROP_INTERFACE

ClassGuid specifies a device interface class. This flag cannot be used with DICLASSPROP_INSTALLER.

Return value

SetupDiSetClassProperty returns TRUE if it is successful. Otherwise, it returns FALSE, and the logged error can be retrieved by calling GetLastError.

The following table includes some of the more common error codes that this function might log.

Return codeDescription
ERROR_INVALID_FLAGS

The value of Flags is invalid.

ERROR_INVALID_CLASS

The device setup class that is specified by ClassGuid is not valid. This error can occur only if the DICLASSPROP_INSTALLER flag is specified.

ERROR_INVALID_REFERENCE_STRING

The device interface reference string is not valid. This error can occur only if the DICLASSPROP_INTERFACE flag is specified.

ERROR_INVALID_REG_PROPERTY

The property key that is supplied by PropertyKey is not valid.

ERROR_INVALID_DATA

An unspecified internal data value was not valid. This error could be logged if the ClassGuid value is not a valid GUID or the property value is not consistent with the property type specified by PropertyType.

ERROR_INVALID_USER_BUFFER

A user buffer is not valid. One possibility is that PropertyBuffer is NULL, and PropertyBufferSize is not zero.

ERROR_NO_SUCH_INTERFACE_CLASS

The device interface class that is specified by ClassGuid does not exist. This error can occur only if the DICLASSPROP_INTERFACE flag is specified.

ERROR_INSUFFICIENT_BUFFER

An internal data buffer that was passed to a system call was too small.

ERROR_NOT_ENOUGH_MEMORY

There was not enough system memory available to complete the operation.

ERROR_NOT_FOUND

An unspecified item was not found. One possibility is that the property to be deleted does not exist.

ERROR_ACCESS_DENIED

The caller does not have Administrator privileges.

 

Remarks

SetupDiSetClassProperty is part of the unified device property model.

SetupAPI supports only a Unicode version of SetupDiSetClassProperty.

A caller of SetupDiSetClassProperty must be a member of the Administrators group to set a device interface property.

SetupDiSetClassProperty enforces requirements on the property-data-type identifier and the property value.

To obtain the device property keys that represent the device properties that are set for a device class on a local computer, call SetupDiGetClassPropertyKeys.

To retrieve a device class property on a local computer, call SetupDiGetClassProperty, and to retrieve a device class property on a remote computer, call SetupDiGetClassPropertyEx.

To set a device class property on a remote computer, call SetupDiSetClassPropertyEx.

Requirements

Version

Available in Windows Vista and later versions of Windows.

Header

Setupapi.h (include Setupapi.h)
