favour C90 and didn't really care for anything more recent.
void HHH(void (*f)(void))
u32 HHH(void (*P)())
Empty parentheses had nothing to do with my point. On line 16 we find: typedef uint32_t u32;
uint32_t != void.
Empty ()s in a declarator were made obsolete in C17 and made equivalentbut not void HHH(void (*f)(void)), eh?
to (void) in C23. Prior to C23 a parameter that is pointer to a
function taking no arguments would have to have been written as
u32 HHH(void (*P)(void))
and after C23 the (probable) intended meaning would have to be written
as
u32 HHH(void (*P)(...))
(Caveat: I'm not properly up to date anymore and, this not beingI have no doubt you're right about (), but that wasn't the point I was making.
comp.lang.c, I may not be corrected by People Who Really Know.)
