Among my geezer-rants is the one about how the
original Windows
tutorial books by Petzold failed to include proper error checking on
the results from Windows calls.
Gee, it would've made the examples less clear, but
it would've saved
a lot of trouble and future (and lingering) bugs for all the
cut-and-paste programmers out there.
Would that really have been a good thing? I'm not convinced. (Mind
you, I'd still more prefer that cut-and-paste programmers' code were
*blatantly* broken, since no matter what's in the examples their code
will be subtly broken much of the time anyway.)
