Function : Unread Notes
NSFDbGetUnreadNoteTable2 - Create an ID Table of unread notes

#include <nsfdb.h>

    char far *UserName,
    WORD  UserNameLength,
    BOOL  fCreateIfNotAvailable,
    BOOL  fUpdateUnread,
    DHANDLE far *rethUnreadList);
Description :

This function is the same as NSFDbGetUnreadNoteTable with the addition of the option to update the unread marks.

An ID Table is created containing the list of unread notes in the open

database for the specified user, and the handle of that ID Table is returned.
Prior to Release 4.5 of Notes, this function will only work with local databases. If both the workstation and the server have Release 4.5 or later installed, this function will also work with remote databases. The user name must be the complete user name, as it would be retrieved from the user's ID file. In particular, if the name is hierarchical, the user name string must be the fully distinguished hierarchical user name. This form of the name may be obtained by calling DNCanonicalize().

The argument fCreateIfNotAvailable controls what action is to be performed if there is no list of unread notes for the specified user in the database. If no list is found and this flag is set to FALSE, the handle returned will be NULL;
if this flag is set to TRUE, the list of unread notes will be created and all notes in the database will be added to the list.

No coordination is performed between different users of the same database. If an application obtains a list of unread notes while another user is modifying the list, the changes made may not be visible to the application.

Unread marks for each user are stored in the client desktop.dsk file

and in the database. When a user closes a database (either through the Notes user interface or through an API program), the unread marks in the desktop.dsk file and in the database are synchronized so that they match. Unread marks are not replicated when a database is replicated. Instead, when a user opens a replica of a database, the unread marks from the desktop.dsk file propagates to the replica database. NSFDbGetUnreadNoteTable2 allows the unread marks to be updated.

Parameters : Input : hDB - Handle of the database.

UserName - Pointer to the fully distinguished user name LMBCS string.

UserNameLength - Number of bytes in the user name string.

fCreateIfNotAvailable - TRUE: If the unread list for this user cannot be found on disk, return all note IDs. FALSE: If the list cannot be found, return an ID Table handle of NULL

fUpdateUnread - TRUE to update unread marks, FALSE to not update unread marks.

Output : (routine) - Return status from this call:

NOERROR - Success ERR_NOT_LOCAL - Attempted to get an unread note table from a remote database. ERR_xxx - Errors returned by lower level functions: (memory management, file operations, network errors, etc.). There are so many possible causes, that it is best to use the code in a call to OSLoadString and display/log the error for the user as your default error handling.

rethUnreadList - Address where the handle for the ID Table will be stored. The application must free this storage using IDDestroyTable().
