How to use the bindings/wasi.errno.SUCCESS function in bindings

constructor() {
    this.env = [];
    let count_and_size = changetype(
      new ArrayBuffer(2 * sizeof())
    );
    let ret = environ_sizes_get(count_and_size, count_and_size + 4);
    if (ret != errno.SUCCESS) {
      abort();
    }
    let count = load(count_and_size);
    let size = load(count_and_size + sizeof());
    let env_ptrs = changetype(
      new ArrayBuffer((count + 1) * sizeof())
    );
    let buf = changetype(new ArrayBuffer(size));
    if (environ_get(env_ptrs, buf) != errno.SUCCESS) {
      abort();
    }
    for (let i: usize = 0; i < count; i++) {
      let env_ptr = load(env_ptrs + i * sizeof());
      let env_ptr_split = StringUtils.fromCString(env_ptr).split("=", 2);
      let key = env_ptr_split[0];
      let value = env_ptr_split[1];
      this.env.push(new EnvironEntry(key, value));
    }
  }
