CEOIDINFO [CEDB] (Compact 2013)

3/26/2014

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

Syntax

typedef struct _CEOIDINFO { 
  WORD wObjType;
  WORD wPad;
  union {
    CEFILEINFO infFile;
    CEDIRINFO infDirectory;
    CEDBASEINFO infDatabase;
    CERECORDINFO infRecord;
  };
} CEOIDINFO; 

Members

• wObjType
  Type of the object. The following table shows 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.

• wPad
  Structure alignment on a DWORD boundary.

• 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 CEDBASEINFO [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 earlier versions (2.12 and earlier) of Windows Embedded Compact, 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. 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.
