    //  This email has two attachments: logo.jpg and faxCover.doc
    int i;
    for (i = 0; i <= email.get_NumAttachments() - 1; i++) {
        printf("%s\n",email.getAttachmentFilename(i));
    }

    //  Let's say we want to save the 1st attachment as "pic.jpg",
    //  and the 2nd attachment as "cover.doc".
    //  Call SetAttachmentFilename for both:
    email.SetAttachmentFilename(0,"pic.jpg");
    email.SetAttachmentFilename(1,"cover.doc");

    //  The SaveAttachedFile method allows you to specify the directory
    //  where the attachment is saved.  To save to the current working
    //  directory, pass a "." for the directory path.  This code
    //  saves each attachment to the current working directory:
    email.SaveAttachedFile(0,".");
    email.SaveAttachedFile(1,".");

    //  Alternatively, we could save all the attachments in a single
    //  call.  The argument to SaveAllAttachments is the directory
    //  path.  In this case, the filenames set by SetAttachmentFilename
    //  are used:
    email.SaveAllAttachments("myAttachments");

    printf("Finished!\n");
