Maybe so, but in this case the issue was calling a function, getting a
return value and then ignoring it -- which the compiler thinks might be
a programmer error. In this case not, hence (void) tells the compiler
(and any code auditor) that you're aware of the return code and consider
it to be irrelevant.
In the second email of my series clang has actually flagged up a bug
because someone has typed != instead of |=
I will put up with a lot of "whining" for that sort of assistance. YMMV
