Every now and then I see an 'unused result' warning come by during
building.
What is the general attitude towards these warnings? Remove them (by
properly checking)? Or leave them be as a kind of documentation -- we
know
we're ignoring the info, but it's good to be reminded?
Under what OS / version and compiler / version and what's the warning?
Paste the full warning(s) you get verbatim.
This question was triggered by
warning: ignoring return value of ‘fwrite’, declared with attribute
warn_unused_result
appearing in diff.c, graph.c, grep.c and several others. I'm using gentoo
linux, gcc 4.5.3.
So the specific question would be, do these fwrites need to be checked?
