Hi
,
I've developed a
dissector for understanding the wireshark , using an imaginary "test"
protocol.
But I'm facing a
problem with it .
When I try to call
another dissector ( I'm calling "gsm_a_dtap") , I'm not getting any display for
the wireshark gui .
The bytes related to
dtap are not at all getting decoded and displayed , but the
remaining portion are all displayed well .
Below is the code
snippet I'm using :
1)
void
proto_reg_handoff_test(void)
{
static gboolean test_initialised =
FALSE;
static dissector_handle_t
test_handle;
if( !test_initialised)
{
test_handle =
create_dissector_handle(dissect_test,proto_test);
test_initialised =
TRUE;
}
else
{
dissector_delete("sccp.ssn", SUA_SSN_TEST,
test_handle);
}
dissector_add("sccp.ssn", SUA_SSN_TEST,
test_handle);
dtap_handle =
find_dissector("gsm_a_dtap");
}
2)call_dissector(dtap_handle, parameter_tvb, pinfo,
test_new_tree);
Can anyone suggest
whether I need to include something else too , to make the DTAP bytes get
displayed properly by calling DTAP dissector from my TEST dissector
.
Regards
