Is this allowed?
% cat foo.c
int foo(void *fvp)
% cc -c foo.c
foo.c: In function `foo':
"foo.c", line 3: warning: dereferencing `void *' pointer
"foo.c", line 3: request for member `_flags' in something not a structure or union
ferror isn't *documented* as being non-function-like[%], and if it were
a real function that would work fine (and indeed s/ferror/(ferror)/
makes the complaint go away).
[%] At least not unless you notice, follow, and carefully read the
stdio(3) SEE ALSO.
Yet just adding a cast to ferror()'s definition isn't right either;
that allows too much instead of too little latitude.
Thoughts? Should ferror be an inline function, maybe? Or am I being
unreasonable in expecting stdio "functions" to act like functions?
