[gdal-dev] overwrite shapefile

[Ramiro Gonzalez]

hello

I want to overwrite a shapefile using ogr(c++). If the dbf file in the
destination shapefile is already open by anather program(exel), the
operation fails in the middle and only the shp and shx files are updated.
How could I check, using OGR, if the dbf(or any other file in the shapefile)
is blocked before I overwrite it?

I tested this with "ogr2ogr -overwrite destination source.shp" and the same
thing happens

Thanks,
Ramiro
