a pointer to void.
That is a pointer to ... aehm ... something, but nobody
knows to what exactly.

I hope that there is at least somebody out there who knows what it is.
If not, why return a pointer to it? ;-)

That's *not* a declaration.
It's a definition.
The declaration
void* someFunction(void);
informs the compiler that someFunction returns a pointer to memory.

This depends upon the definition
void* someFunction(void) {
return malloc(sizeof(int));
}
for example.

Yes, it is.

It's both.

Oh, yes it certainly is (barring the syntax error)
See 3.1 / 2 and 7 / 1.

Yes, it's that as well.

So does the declaration posted by the OP.

The line with the three periods.
If you want to use such to indicate e.g.
"other stuff goes here", put it in a comment.
I know this case isn't really a good example, but
you'll find that more help is available if posted
code can be copy-pasted and compiled verbatim.
