Wireshark-dev: [Wireshark-dev] Problems in calling a message from RANAP dissector
Date: Tue, 22 Jan 2008 16:24:12 +0530

Hi ,


I have my test dissector , running over SUA , in TLV ( tag length value) format. In one of the messages, I want to add an existing RANAP ( asn.1 format) message along with the other parameters of my protocol. The coding of one of the messages in which I have called RANAP message goes like this:


dissect_message(tvbuff_t *tvb,int offset ,proto_tree *xxx_tree,packet_info *pinfo)




asn1_ctx_t actx;


asn1_ctx_init(&actx, ASN1_ENC_PER, TRUE, pinfo);

offset = dissect_ranap_ResetResource(tvb, offset, &actx, macic_tree, hf_macic_ranap_resetResource);


proto_tree_add_item(xxx_tree, hf_xxx_clust,tvb, offset, en, FALSE);

offset = offset + len;




I have seen this way of implementation in MEGACO , trying to call a h245 message. But the RANAP message is not dissected properly and also I am not able to get the remaining parameters in the message. Could somebody confirm whether it is the right way to call a message from a different dissector.
