atomising dbfadd shpadd operations

[Cameron Shorter]

Hi,

I'm now working toward a web based updating of mapserver shapefiles.

I notice that there are a few programs (dbfadd, shpadd, etc) in
ms_3.2/shapelib which I will probably use.  I don't suppose there is some
documentation for these programs floating around are there? :)

The one problem that I see is if an operator aborts an operation half way
through the updating of the .dbf and .shp files, and only one of the files
is updated, or it is partially updated.  Ie we need to ensure the updates
are done fully or not at all, or if the update only partially completes
then the database is corrected next time the database is accessed.

Has anyone addressed this problem before?
