DLbind_req(3dlpi)                                  DLbind_req(3dlpi)


       NAME
             DLbind_req - process DL_BIND_REQ primitive

       SYNOPSIS
             DLbind_req(queue_t *q, mblk_t *mp)

          Parameters
            q           pointer to the write queue

            mp          message pointer

       DESCRIPTION
             This function processes the DL_BIND_REQ primitive.  The latter
             is used to request the provider to bind a SAP to the Stream.
             It also activates the Stream for data transfer requests.  It
             is an error if the Stream is already bound to another SAP.  In
             this example a DL_OUTSTATE error is returned by calling
             DLerror_ack().

             Only a privileged user can bind to a promiscuous SAP, or, to a
             SAP that is already bound.  If the user is not privileged, a
             DL_ACCESS error is returned in the former case and DL_BOUND
             error in the latter, by calling DLerror_ack().

             The mac_type field of the DL_sap_t structure is updated to
             reflect the SAP type as either DL_ETHER or DL_CSMACD.  The
             max_spdu field is initialized based on the SAP type.  The SAP
             is also added to the list of valid SAPS.  The state of the SAP
             is initialized and a reply is sent back in the form of a
             DL_BIND_ACK message.  If enough memory is not present for a
             reply, the request is dropped.  The dl_sap field of the
             dl_bind_ack_t structure contains the address of the SAP bound
             to the Stream in host order.

          Response
            error codes DL_OUTSTATE, DL_ACCESS, DL_BOUND, DL_BADADDR

            DL_BIND_ACK sent upstream
