T_EXDATA_IND(D7tpi)


T_EXDATA_IND -- Expedited Data Indication

Synopsis

This message consists of one M_PROTO message block followed by one or more M_DATA message blocks containing at least one byte of data. The format of the M_PROTO message block is as follows:
   struct T_exdata_ind {
   	long PRIM_type;  /* always T_EXDATA_IND */
   	long MORE_flag;  /* indicates more data in ETSDU */
   }

Description

This primitive indicates to the transport user that this message contains an expedited transport interface data unit. One or more expedited transport interface data units form an expedited transport service data unit.

This primitive has a mechanism which indicates the beginning and end of an expedited transport service data unit. However, not all transport providers support the concept of an expedited transport service data unit.

Parameters


PRIM_type
identifies the primitive type.

MORE_flag
when greater than zero, indicates that the next T_EXDATA_IND primitive is also part of this expedited transport service data unit.

Modes

Only connection-mode.
