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));
