Hello.

Oh well, these things happen. Actually, supporting 'hh', 'z', etc. in printf
wasn't actually that hard. I wrote some test cases for them (see
tests/libc/ansi/stdio/printf2.c), which we can still use. It is probably worth
checking that the test behaves the same way before and after applying your
patch.

I also added support to scanf (well, _doscan) for them.

Is there a similar positional patch for scanf? From looking at the Single Unix
Specification, version 2, it seems that scanf supports %n$ too.

I think removing my code from _doprnt may be the easiest way to do it. I can't
remember if I made any bugfixes at the same time. I don't think so. But it's
worth checking the comments in CVS log and doing some diffs. You could use the
web interface to CVS for that:

http://www.delorie.com/bin/cvsweb.cgi/djgpp/src/libc/ansi/stdio/doprnt.c

I fixed some bugs in _doprnt or _doscan or perhaps both. I can't really
remember. IIRC I fixed a buffer-overflow bug in _doscan, when I added support
for 'hh', 'z', etc.

OK.

Thanks, bye, Rich =]
