void*

[Guybrush Threepwood]

a function declared as

void* someFunction()
{
....
}

what does it exactly return?

 

[Karl Heinz Buchegger]

a function declared as

void* someFunction()
{
...
}

what does it exactly return?

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

 

[Rolf Magnus]

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? ;-)

 

[E. Robert Tisdale]

a function declared as

void* someFunction()
{
...
}

That's *not* a declaration.
It's a definition.
The declaration

void* someFunction(void);

informs the compiler that someFunction returns a pointer to memory.

what does it exactly return?

This depends upon the definition

void* someFunction(void) {
return malloc(sizeof(int));
}

for example.

 

[Jeff Schwab]

That's *not* a declaration.

Yes, it is.

It's a definition.

It's both.

 

[Mike Wahler]

That's *not* a declaration.

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

It's a definition.

Yes, it's that as well.

The declaration

void* someFunction(void);

informs the compiler that someFunction returns a pointer to memory.

So does the declaration posted by the OP.

What syntax error?

 

[Mike Wahler]

What syntax error?

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.
