This structure contains information about an object in the object store or database volume.

Syntax

typedef struct _CEOIDINFOEX { 
  WORD wVersion;
  WORD wObjType;
  union {
    CEFILEINFO infFile;
    CEDIRINFO infDirectory;
    CEDBASEINFOEX infDatabase;
    CERECORDINFO infRecord;
  };
} CEOIDINFOEX;

Members

  • wVersion
    Version of this structure. Applications must set wVersion to 1.

  • wObjType
    Type of the object. The following table lists possible values.

    Value Description

    OBJTYPE_DATABASE

    Indicates that the object is a database.

    OBJTYPE_DIRECTORY

    Indicates that the object is a directory.

    OBJTYPE_FILE

    Indicates that the object is a file.

    OBJTYPE_INVALID

    Indicates that the object store contains no valid object that has this object identifier.

    OBJTYPE_RECORD

    Indicates that the object is a record inside a database.
  • infFile
    A CEFILEINFO structure that contains information about a file. This member is valid only if wObjType is OBJTYPE_FILE.
  • infDirectory
    A CEDIRINFO structure that contains information about a directory. This member is valid only if wObjType is OBJTYPE_DIRECTORY.
  • infDatabase
    A CEDBASEINFOEX (CEDB) structure that contains information about a database. This member is valid only if wObjType is OBJTYPE_DATABASE.
  • infRecord
    A CERECORDINFO (CEDB) structure that contains information about a record in a database. This member is valid only if wObjType is OBJTYPE_RECORD.

Remarks

In Windows CE 2.12 and earlier, OIDs were assigned to objects in other file systems, such as the FAT file system. These OIDs were guaranteed to be unique within a volume, but not across multiple volumes. Effective with Windows CE 3.0, the only file and directory objects that have valid, unique OIDs are in the object store. Database objects, on any file system, have valid, unique OIDs.
