ISDN_DATA_B3.ISDN_IND -- ISDN incoming data indication

Synopsis

   #include <sys/stream.h>
   #include <sys/mdi.h>
   #include <sys/types.h>
   #include <sys/scoisdn.h>
   
   typedef struct isdn_data_b3_ind
   {
       isdnNCCI_t      ncci;
       isdnData_t      data;
       isdnDataLen_t   dataLen;
       isdnHandle_t    dataHandle;
       isdnFlags_t     flags;
   } isdn_data_b3_ind_t;

Description

The ISDN_DATA_B3.ISDN_IND message consists of one M_PROTO(D7str) message block indicating incoming data within a logical connection, followed by an M_DATA(D7str) block containing the data. The logical connection is identified by the ncci parameter. The length of the incoming data area is indicated by the dataLen parameter. The ISDN driver issues a handle to this data using the dataHandle parameter. Upon the subsequent confirmation by a ISDN_DATA_B3.ISDN_RESP(D7isdn), this handle must also be supplied by the application. Additional information -- such as more data, delivery confirmation, etc. -- is supplied by the flags parameter, if available.

The data transport does not support re-assembly functions.

Parameters

ncci: Network control connection identifier; see isdnNCCI(D4isdn).
data: Data pointer -- not used; see isdnData(D4isdn).
dataLen: Data length; see isdnData(D4isdn).
dataHandle: Data handle; see isdnData(D4isdn).
flags: Flags; see isdnFlags(D4isdn).
