["Anders Broman" <anders.broman@xxxxxxxxxxxx>]

Hi,

It vas ANSI TCAP right?

How about this code from packet-ansi_map-template.c

 

static void range_delete_callback(guint32 ssn)
 {
 if (ssn) {
  delete_ansi_tcap_subdissector(ssn , ansi_map_handle);
   add_ansi_tcap_subdissector(ssn , ansi_map_handle);
    }
 }

 

 static void range_add_callback(guint32 ssn)
 {
 if (ssn) {
   add_ansi_tcap_subdissector(ssn , ansi_map_handle);
 }
 }

 

 void
 proto_reg_handoff_ansi_map(void)
 {
     static int ansi_map_prefs_initialized = FALSE;
     data_handle = find_dissector("data");
    
     if(!ansi_map_prefs_initialized)
     {
  ansi_map_prefs_initialized = TRUE;
  ansi_map_handle = create_dissector_handle(dissect_ansi_map, proto_ansi_map);
     }
     else
     {
  range_foreach(ssn_range, range_delete_callback);
     }
    
     g_free(ssn_range);
     ssn_range = range_copy(global_ssn_range);
 
     range_foreach(ssn_range, range_add_callback);
 }

void proto_register_ansi_map(void) {
:

  ansi_map_module = prefs_register_protocol(proto_ansi_map, proto_reg_handoff_ansi_map);
   

 

  prefs_register_range_preference(ansi_map_module, "map.ssn", "ANSI MAP SSNs",
        "ANSI MAP SSNs to decode as ANSI MAP",
        &global_ssn_range, MAX_SSN);
:

Subject: [Wireshark-dev] dissect_add error for tcap.ssn

Hello ,

 

I am trying to include a dissector using my asn.1 format for a test protocol which runs over TCAP layer.

The test.asn file was written and compiled along with packet-test-template.c file in the ..wireshark/asn1/test directory .

 

But I am facing a poblem , an error is displayed with respect to "dissector_add" .

Here is how the "dissector_add" portion of my code looke like :

 

void proto_reg_handoff_tsrp(void){
  static int test_prefs_initialized = FALSE;
  if (!test_prefs_initialized) {
    test_prefs_initialized = TRUE;
    test_handle = create_dissector_handle(dissect_test, proto_test);}
   else
        dissector_delete("tcap.ssn", TCAP_SSN_TEST, test_handle);

 dissector_add("tcap.ssn", TCAP_SSN_TEST, test_handle);

}

Request you to please help me identify the mistake.

 

Regards ,

Atdev
