Thanks, Phil, for respond.
I agree: docs are pure. I have the same manual.txt for libgeotiff.

Still can not find any reference for return from TIFFGetField(tif, TIFFTAG_GEOASCIIPARAMS, &data)
command. The other two return number of elements as a parameter:
TIFFGetField(tif, TIFFTAG_GEOKEYDIRECTORY, &size, &data);
TIFFGetField(tif, TIFFTAG_GEODOUBLEPARAMS, &size, &data);

TIFFGetField() description in tiff-3.8.2\html\man\TIFFGetField.3tiff.html shows
in "Autoregistered tags" sample that ascii tag should be handled the same way. But 
real code is different.

I want to use TIFF approach to handle tags (shorts, doubles, ascii) as an arrays
rather then GTIFFKeySet/GTIFFKeyGet for each tag. Thanks to gdal it handles geoTiff

Any help, please!

Sorry, I meant to give you this reference so you can download the 
GeoTiff library, which I believe includes documentation:
