FWIW, a return value can be cast to (void) to tell explicitly that
it doesn't matter.  While ignoring a return value from a well-known
function, such as close(), looks mostly OK to code readers (the
author knows what he's doing, they think,) it may not be the case
for a local function of limited application.
