Jaap,
Yeah the handle coould be used some where else
void
proto_reg_handoff_atm(void)
{
dissector_handle_t atm_handle, atm_untruncated_handle;
/*
* Get handles for the Ethernet, Token Ring, Frame Relay, LLC,
* SSCOP, LANE, and ILMI dissectors.
*/
eth_withoutfcs_handle = find_dissector("eth_withoutfcs");
tr_handle = find_dissector("tr");
fr_handle = find_dissector("fr");
llc_handle = find_dissector("llc");
sscop_handle = find_dissector("sscop");
lane_handle = find_dissector("lane");
ilmi_handle = find_dissector("ilmi");
data_handle = find_dissector("data");
fp_handle = find_dissector("fp");
atm_handle = create_dissector_handle(dissect_atm, proto_atm);
dissector_add("wtap_encap", WTAP_ENCAP_ATM_PDUS, atm_handle);
atm_untruncated_handle =
create_dissector_handle(dissect_atm_untruncated,
proto_atm);
dissector_add("wtap_encap", WTAP_ENCAP_ATM_PDUS_UNTRUNCATED,
atm_untruncated_handle);
}
But lets say if I don't use those dissector handle right away, I need
not find them immediately .
For instance 'fr_handle'in the atm reg . I believe it is just for the
future use and not MANDATORY this point of code.Am I right.
You see I am in the process of registering my first dissector,hnce the
stumble :)
Thanks for pointing, made a silly mistake, I've removed and changed the
password :)

Hi,
For one the eth_handle is most likely a module global variable, so used
elsewhere. Could you name the dissector you saw this in?
The other thing to notice is that it is not very smart to quote your
registration info, including password, in a public mailing list.....
Better change is REAL SOON NOW.
Thanx,
Jaap
