   Thanks for your help. According to the official document, I implement get_quote_func() just in the untrusted app. I try many different ways to initialize the paramter, but none of them work.. 
   
   Following the sample code provided by ue-ra, I wrote a version. But it has the same problem:
   ```
           // Init Enclave parameter
           let quote_type = sgx_quote_sign_type_t::SGX_LINKABLE_SIGNATURE;
           let spid = sgx_spid_t::default();
           let p_spid = &spid as *const sgx_spid_t;
   
           // Optional Output: qe_report could be null
           let mut qe_report = sgx_report_t::default();
   
           const RET_QUOTE_BUF_LEN : u32 = 2048;
           let mut return_quote_buf : [u8; RET_QUOTE_BUF_LEN as usize] = [0;RET_QUOTE_BUF_LEN as usize];
           let p_quote = return_quote_buf.as_mut_ptr();
   
           let max_len = RET_QUOTE_BUF_LEN;
           let mut quote_len : u32 = 0;
           let p_quote_len = &mut quote_len as *mut u32;
   
           // NULL Pointer
           let (p_sigrl, sigrl_len) = (ptr::null() as *const u8, 0);
   
           let quote_nonce = sgx_quote_nonce_t::default();
           let p_nonce = &quote_nonce as * const sgx_quote_nonce_t;
   
           // Init Enclave
           let mut ti : sgx_target_info_t = sgx_target_info_t::default();
           let mut eg : sgx_epid_group_id_t = sgx_epid_group_id_t::default();
           let mut rt : sgx_status_t = sgx_status_t::SGX_ERROR_UNEXPECTED;
   
           let res = unsafe {
               rust_init_quote(&mut ti as *mut sgx_target_info_t,
                                &mut eg as *mut sgx_epid_group_id_t)
               };
   
           println!("eg = {:?}", eg);
   
           if res != sgx_status_t::SGX_SUCCESS {
               println!("Get error when init quote");
               return;
           }
   
           let result = unsafe {
               rust_get_quote(p_sigrl,
                              sigrl_len,
                              p_report,
                              quote_type,
                              p_spid,
                              p_nonce,
                              &mut qe_report as *mut sgx_report_t,
                              p_quote,
                              max_len,
                              p_quote_len)
               };
   ```
   Really confused. I was wondering whether it is because that I use a simulation mode.
