TypeError: error setting argument 2 - writePointer: Bufferinstance expected as third argument

electron ffi 调第三方动态库报“TypeError: error setting argument 2 - writePointer: Bufferinstance expected as third argument”

原因是我定义了一个结构体，调函数传参数需要传这个结构体的指针

 const ec_image_t = Struct({
       。。。。
    })

 let image_a = new ec_image_t();

ret = match.ec_face_match_get_feature(handleAddress,image_a ,ref.alloc(m_face_feature1));

函数定义image_a 需要传指针，传错了，改成以下可以通过

ret = match.ec_face_match_get_feature(handleAddress,image_a.ref() ,ref.alloc(m_face_feature1));

.ref()获取指针
