Hi,
How about moving this line
foo_handle = create_dissector_handle(dissect_foo, proto_foo);
Before:
dissector_add("q931.ie",0xFE,foo_handle);
/*0xFE is identifier of my protocol*/
Regards
Anders
Hi!!!
I'm writing a plugin for our program's own protocol, which encapsulates a whole 'q931' package in user-user information element (look at the end of massage in red ).
In the first time ; I would just write a small program to check the right place to register my Protocol, and display :
Q.931
………………………………
……………………………..
…………………………….
User-user
Information element: User-user
Length: 15
Protocol discriminator: User-specific protocol
User information:
mytype protocol ( 0xFE)
Texte: B30C07498131323533357F0182
I register my protocol with the table (q931.ie ) like this :
dissector_add(dissector table name, value in that table, mytype_handle)
====>dissector_add("q931.ie",0xFE,foo_handle)
when Wireshark build !! I’ don’t get error, but It has no effect on Wireshark.
This function is called to register my protocol:
proto_reg_handoff_ipnet(void)
{
static gboolean initialized = FALSE;
if (!initialized) {
q931_ie_handle = find_dissector("q931.ie");
dissector_add("q931.ie",0xFE,foo_handle);
/*0xFE is identifier of my protocol*/
foo_handle = create_dissector_handle(dissect_foo, proto_foo);
initialized = TRUE;
}
};
My question :* you think that it’s the good table ?!!!
* How can I register my Protocol correctly?
