I am trying to call the following C function (simplified version from a C 
library) from Go,
and I got compiler errors:
typedef void device_t;
void open(device_t **dev) {
}

*Go Function*:
func Open() {
   var dev C.device_t
   C.open(&&dev)
}

*Compiler (v1.17) error:*
cannot use _cgo0 (type **_Ctype_void) as type *unsafe.Pointer in argument 
to _Cfunc_open

How to fix that?
Regards.
