Function : File Attachment
NSFNoteExtractFileExt - Extract a file from an item in a note.

#include <nsfnote.h>

    NOTEHANDLE  note_handle,
    BLOCKID  item_blockid,
    const char far *file_name,
    ENCRYPTION_KEY far *DecryptionKey,
    WORD  wFlags);
Description :

Creates a disk file from the contents of an attached item (referenced by its BLOCKID). The BLOCKID can be easily obtained by item name using NSFItemInfo.
The file_name parameter specifies the path, file name, and extension of the file to be created. If only a file name and extension are supplied, the file will be created in the current working directory.

Note: NSFNoteExtractFileExt should be deprecated from Notes/Domino 8.0.1. The preferred function to use in their place is NSFNoteCipherDecrypt.

Parameters : Input : note_handle - Handle of note from which disk file will be extracted.

item_blockid - BLOCKID of the attachment item from which file is to be extracted.

file_name - A null-terminated file name of the file that will be created.

DecryptionKey - Use NULL if the attachment is not encrypted. Otherwise, use a pointer to the ENCRYPTION_KEY structure returned by NSFNoteDecrypt.

wFlags - The possible values for the wFlags are defined by the NTEXT_xxx symbol.

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

NOERROR - Successfully extracted file.

ERR_ENCODING - Unknown type of compression technique.

ERR_NOEXTRACT_ENCRYPTED - You must supply the decryption key in order to extract this file.

ERR_NOTE_BADATTSIGN - Attachment has been modified or corrupted since signed!

ERR_xxx - Errors returned by lower level functions. 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.
