There is no such thing as an "official newsgroup program", at
least not in comp.lang.c

Well, it's listed on the group website, so I'd say that's official.


(gdb) bt

It seems very unlikely that Eric would have written his code to
call into the "getline" function in the GNU C library, which is
what this backtrace is showing. I think that you did not compile
and link the test program correctly.

GNU lib'c getline and Eric's getline evidently have different
interfaces, judging from the line of source code above.

I don't believe there's a standard library function called getline. If
there is, wouldn't it be better if Dr Sosman's version either had a
different name, or followed the same interface?
