Hello,
I have a problem with the declaration of a function.
This is how I declare the function :

c:63: void foo(threadpool *tp,void (*func)(void*), (void*)arg);

Inside main, I call it like this:

main(){
..........

threadpool y;

c:104: foo(y,foo2,(void*)x);

}

and here is the foo2,and foo:

c:109:void foo(threadpool *tp,void (*func)(void*), (void*)arg){.........}
c:110: void * foo2(void *arg) {......}

gcc gives me those things:

c:63: error: expected declaration specifiers or ‘...’ before ‘(’ token
c:104: warning: passing argument 2 of ‘foo’ from incompatible pointer type
c:63: note: expected ‘void (*)(void *)’ but argument is of type ‘void * (*)(void *)’
c:104: error: too many arguments to function ‘foo’
c:110: error: expected declaration specifiers or ‘...’ before ‘(’ token
c:110: error: expected identifier or ‘(’ before ‘{’ token

Generally,foo is a function used to access a threadpool and takes a thread , passes to it the function foo2 to execute it.

I dont know what the problem is,even if I tried a lot of things.Please answer as soon as possimple because i m pressed in time!
thanks in advance
