Should be
typedef uint64_t MediaHandle
of course.

This one is better formulated to return a value of proper type
representing the handle:
func GetMediaFromDB(filename *C.char) C.MediaHandle {
c_struct_media := &C.struct_Media{}
handle := C.MediaHandle(uintptr(unsafe.Pointer(c_struct_media)))
media[handle] = c_struct_media
return handle
}
