             *pdu_ptr;

             void   free_SMUX_ClosePDU(close_ptr) SMUX_ClosePDU *close_ptr;

             void   free_SMUX_RReqPDU(rreq_ptr) SMUX_RReqPDU *rreq_ptr;

             void   free_SMUX_RRspPDU(rrsp_ptr) SMUX_RrspPDU *rrsp_ptr;

             void   free_SMUX_GetPDU(get_ptr) SMUX_Data_PDU *get_ptr;

             void   free_SMUX_SOutPDU(sout_ptr) SMUX_SOutPDU *sout_ptr;

       DESCRIPTION
             decode_SMUX_PDU takes an SMUX PDU from the packet received and
             parses the information into the library's internal PDU format,
             including all VarBind instances. If this routine fails, it
             returns NULL.

             encode_SMUX_PDU creates an ASN.1 encoded SMUX PDU from the
             SMUX PDU structure specified by pdu_ptr.  ASN.1 encoding is
             required for the transfer of an SMUX PDU from an agent to a
             peer and vice versa.  encode_SMUX_PDU traces down the
             structure of VarBinds that have been added to the SMUX PDU and
             builds the ASN.1 encoding of the SMUX PDU in the packlet
             pointer of the SMUX PDU data structure specified by pdu_ptr.
             When this ASN.1 encoding is complete, SMUX PDU processing is

      smux_pdu(3N)                                            smux_pdu(3N)


            complete, and the structure is ready to be transferred.  If
            successful, encode_SMUX_PDU returns 0; if unsuccessful, it
            returns -1.

            free_SNMP_SMUX_pdu frees all memory associated with the PDU
            header data structure, including the actual packlet and all
            the VarBindList structures that were linked to the PDU. To
            accomplish this, free_SNMP_SMUX_pdu invokes one of the
            following functions, depending on the the type of PDU that
            pdu_ptr points to: free_SMUX_SimpleOpen, free_SMUX_ClosePDU,
            free_SMUX_RReqPDU, free_SMUX_RRspPDU, free_SMUX_GetPDU,
            free_SMUX_SOutPDU, or free_SMUX_TrapPDU.
