I'm looking for a sample code that writes a tiff with the EXIF metadata inside.

Can you help me?

I haven't seen a response to this question yet, and I don't have any libtiff sample code that will do this, but adding EXIF information to a TIFF image is easy using the Image::ExifTool Perl library. For example, to add XResolution, YResolution and ResolutionUnit:

use Image::ExifTool;
my $exifTool = new Image::ExifTool;
$exifTool->SetNewValue('EXIF:XResolution', 300);
$exifTool->SetNewValue('EXIF:YResolution', 300);
$exifTool->SetNewValue('EXIF:ResolutionUnit', 'inch');
$exifTool->WriteInfo('image.tiff');
