Will this leak memory?

Hello,

I have the following code:

foo_ptr * alloc_foo(int size, ...) {
/*
This function allocates an instance of the foo_ptr type,
and returns a pointer to the newly allocated storage.
*/
}

void free_foo(foo_ptr *foo) {
....
}

void func(const foo_ptr *foo) {
/*
Do something (read-only) on the foo object.
*/
}


int main(void) {

func( alloc_foo(10 , ...) );

}

Now my question is wether the memory set aside by alloc_foo() will
leak. Since I have not stored a pointer to this memory I can not free
it myself. If this will indeed leak memory I will have to do it like
this:

{
foo_ptr *tmp_foo = foo_alloc(10 , ...);
func(tmp_foo);
free_foo(tmp_foo);
}

Which is considerably less elegant.

Best regards

Joakim
