problem with (void *) argument

[lordken]

Hi everybody.

I'm new in C programming, and I've faced a strange problem which is :
I have a method --> void message(mail *m, void *item)
the problem is that when i try to call it by --> p = message(&mb, &item);
where mb is of type mail (structure)
p is a pointer of type mail
and item is of any other type (let us say: int).

when i try to compile the following error appears:
void value not ignored as it ought be.

could anyone tell me what is the problem here.

Yes, your method is

void message(mail *m, void *item)

You have given the return type as void this means the function returns nothing but you have tried to assign it to a variable. That is why you are getting the error.

It you are meant to return a void pointer then you are missing a *

void *message(mail *m, void *item)
