Describes the properties of a directory entry id.

Header file:

entryid.h

#pragma pack(4)
typedef struct _dir_entryid
{
    BYTE abFlags[4]; 
    MAPIUID muid; 
    ULONG ulVersion; 
    ULONG ulType; 
    MAPIUID muidID; 
}   DIR_ENTRYID, *LPDIR_ENTRYID; 
#pragma pack()

abFlags

A bitmask of flags that provides information describing the object. For more information, see the description of the abFlags field of an ENTRYID structure.

muid

GUID that identifies the store provider.

ulVersion

The version number of the DIR_ENTRYID structure. Must be set to CONTAB_VERSION.

ulType

An integer representing the directory entry ID type. It must be one of the following values:

Name

Description

CONTAB_ROOT

The root folder for a MAPI address book.

CONTAB_SUBROOT

A subfolder contained within the root folder of the MAPI address book object.

CONTAB_CONTAINER

muidID

A GUID that identifies the logon object.

The structures DIR_ENTRYID and CONTAB_ENTRYID are identical, except for the ulType member. The contents of the ulType member determine which structure is appropriate for the remaining fields.
