Hi Jerry: I noticed some garbage after the device name for the Ada thick and thin example 31 results in stderr. In contrast to this less-than-ideal result for plgfnam, plgver produces good looking results for Ada thick and thin example 1 library version. There plgver is called using the functional form without arguments so I tried to do the same for plgfnam and it didn't work.
IMO, plgdev, plgfnam, and plgver (and their thick versions) should all be implemented identically in the bindings since they all produce strings. Accordingly I have made some Ada bindings changes as of revision 9259. Note, there was no way I could get the procedure version of plgfnam to work with the To_Ada second argument True, so I uniformly set that to False for all procedure versions of plgdev, plgver, and corresponding thick versions in analogy with the existing plgfnam procedural version. Unless the analogy is wrong for some unknown reason this should be the right thing to do, but note we do not test the procedural versions of anything but plgfnam so these API changes are untested by any of our tests. I also changed the Ada 31st examples to use the new function version of plgfnam (and its thick counterpart) when outputting results to stderr, and it no longer has garbage after the output name. Thus, everything seems to be working correctly with my changes with no garbage output results for examples 31. However, I am programming by analogy here with no deep understanding of what I am doing so will you please review my changes? N.B. I am pretty sure you could stick strictly with the procedural form of plgfnam (and thick counterpart) in Ada examples 31 if you used some string-trimming function to get rid of the trailing garbage for the filename output to stderr. However, please do not do that since I think the current implementation in Ada examples 31 is a better way to go since it exercises both the procedural and functional forms of plgfnam while also getting rid of the trailing garbage in stderr.
