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

This primitive has a mechanism which indicates the beginning and end of

However, not all transport providers support the concept of an
expedited transport service data unit.

next T_EXDATA_IND
primitive is also part of this expedited transport service data
unit.
