  • Article

The ACX_OBJECTBAG_CONFIG_FLAGS enumeration defines the configuration for an AcxObjectBag.

Syntax

typedef enum _ACX_OBJECTBAG_CONFIG_FLAGS {
  AcxObjectBagConfigNoFlags,
  AcxObjectBagConfigEnableReads,
  AcxObjectBagConfigEnableWrites,
  AcxObjectBagConfigFailIfExist,
  AcxObjectBagConfigOpenWithHandle,
  AcxObjectBagConfigValidFlags
} ACX_OBJECTBAG_CONFIG_FLAGS;

Constants

 
AcxObjectBagConfigNoFlags
Indicates that no config flags are set.
AcxObjectBagConfigEnableReads
Indicates that reads are enabled.
AcxObjectBagConfigEnableWrites
Indicates that writes are enabled.
AcxObjectBagConfigFailIfExist
Indicates that if an ACXOBJECTBAG with the same identity is already present, creation should fail instead of opening the existing one.
AcxObjectBagConfigOpenWithHandle
Indicates to open the ACXOBJECTBAG whose handle is specified in the configuration structure.
AcxObjectBagConfigValidFlags
For internal validation, do not use.

Remarks

Example

This example shows the use of ACX_OBJECTBAG_CONFIG_FLAGS.

        GUID                    uniqueId = { 0 };
        UNICODE_STRING          uniqueIdStr = { 0 };
        UNICODE_STRING          pnpDeviceId = { 0 };
        ACX_OBJECTBAG_CONFIG    objBagCfg;

        DECLARE_CONST_ACXOBJECTBAG_SYSTEM_PROPERTY_NAME(UniqueID);

        ACX_OBJECTBAG_CONFIG_INIT(&objBagCfg);
        objBagCfg.Handle = CircuitConfig->CompositeProperties;
        objBagCfg.Flags |= AcxObjectBagConfigOpenWithHandle;

        WDF_OBJECT_ATTRIBUTES_INIT(&attributes);
        ACXOBJECTBAG objBag = NULL;

        RETURN_NTSTATUS_IF_FAILED(AcxObjectBagOpen(&attributes, &objBagCfg, &objBag));
