FLATENTRY

Platform SDK: MAPI

The FLATENTRY structure is an ENTRYID structure plus a byte count that specifies the size of the ENTRYID structure.

Header file:	MAPIDEFS.H
Related macros:	cbFLATENTRY CbNewFLATENTRY

typedef struct 
{ 
     ULONG  cb; 
     BYTE   abEntry[MAPI_DIM]; 
} FLATENTRY, FAR *LPFLATENTRY;

cb: Count of bytes in the abEntry member.
abEntry: The complete entry identifier, including the array of flags and binary data.

A FLATENTRY structure is similar to an ENTRYID structure. However, there are some differences:

A FLATENTRY structure stores the size of the entry identifier; ENTRYID does not.
A FLATENTRY structure stores the flag data together with the rest of the entry identifier; ENTRYID stores them separately.
A FLATENTRY structure is used to store an entry identifier in a file or pass it in a stream of bytes whereas an ENTRYID structure is used by the IMAPIProp interface methods and by the following OpenEntry methods:
IABLogon::OpenEntry
IAddrBook::OpenEntry
IMAPIContainer::OpenEntry
IMAPISession::OpenEntry
IMAPISupport::OpenEntry
IMsgStore::OpenEntry
IMSLogon::OpenEntry
A FLATENTRY structure is used to store an entry identifier in a file or pass it in a stream of bytes. An ENTRYID structure is used to store an entry identifier on disk.
