Detailed Description
Send progress.
Structure holding send progress. For mtms unable to provide detailed progress information, iProgressMax and iProgress must be zeroed. This will then allow the client to check for this case and display a busy status dialog as opposed to a progress dialog. If the mtm is capable of detailed progress, iProgressMax should be set to the total number of units to be sent and iProgress the number of units sent.
