isdnData -- ISDN B3 data pointer

isdnDataLen- ISDN B3 data length parameter

isdnDataHandle- ISDN B3 data handle parameter

Synopsis

   #include <sys/types.h>
   #include <sys/scoisdn.h>
   
   typedef isdnDword_t isdnData_t;
   

   typedef isdnWord_t isdnDataLen_t;
   

   typedef isdnWord_t isdnHandle_t;

Description

The following B3 data parameters are provided:

isdnData_t: exchanges a 32-bit pointer to the data area. Not used in this STREAMS implementation.
isdnDataLen_t: specifies the length of the data.
isdnHandle_t: identifies the data area in data exchange messages. That is, it is used to match B3 data REQUEST with CONFIRMATION messages, and INDICATION with RESPONSE messages.

These types are used by:

ISDN_DATA_B3.ISDN_REQ(D7isdn)
ISDN_DATA_B3.ISDN_CONF(D7isdn)
ISDN_DATA_B3.ISDN_IND(D7isdn)
ISDN_DATA_B3.ISDN_RESP(D7isdn)
