[gdal-dev] Get hold of TIFF structure

[Even Rouault]

GDALDataset::GetInternalHandle() on a GTiff dataset will return a TIFF* handle.
But be careful. If you use GDAL compiled with internal libtiff (libtiff 4.X),
you must also link your application against libtiff 4.X, or export the libtiff
symbols of the internal version of GDAL, otherwise chaos will happen.

Why do you want to access the TIFF handle ? Is there information you cannot
access through GDAL API ?
