Discarded Function Values (To Cast or Not to Cast)

[Chris Kern]

I suspect this is not a novel inquiry, but I can't remember any
previous discussion. . . .

My compiler (pcc) is agnostic about discarding the value from a
function call.  Lint, of course, protests.

If it's my function, I presumably will declare it to be void if
it doesn't return a value and will use the value if it does return
one.  But what about a standard library function whose value I
(perhaps recklessly) wish to ignore?  Should I cast the function
call to void, or am I just indulging in the trivial luxury of
silencing lint?
