Hello, I am looking for a little clarification with respect to the message delivery status in smpp. While browsing through the source file (gw/smsc/smsc_smpp.c) in handle_pdu() function , in case:deliver_sm , we call the function handle_dlr and the last
argument which is passed is pdu->u.deliver_sm.message_state. I am not able to understand from where we get the message_state as there is no such parameter specified in the SMPP 3.4 specification for DELIVER_SM message. can someone correct me in the understanding the logic behind this part ? Regards, Basileis
