The double is passed by value; so dereferencing it works fine.  But the
struct is passed by reference (as are *all* structures in C!).  In reality,
you need to pass a "struct qwert *" to the function.  Normally, the compiler
takes the reference automatically, but you are trying to do this in reverse.
Thus, it does not work; you simply can't pass a structure by value.
