T_UNITDATA_IND(7tpi) T_UNITDATA_IND(7tpi)
NAME
T_UNITDATA_IND - Unitdata Indication
SYNOPSIS
This message consists of one M_PROTO message block followed by
zero or more M_DATA message blocks where each M_DATA message
block contains at least one byte of data. The format of the
M_PROTO message block is as follows:
struct T_unitdata_ind {
long PRIM_type; /* always T_UNITDATA_IND */
long SRC_length; /* source addr length - */
long SRC_offset; /* source addr offset */
long OPT_length; /* options length - */
long OPT_offset; /* options offset */
}
DESCRIPTION
This primitive indicates to the transport user that a datagram
has been received from the specified source address.
Parameters
PRIM_type
identifies the primitive type.
SRC_length
is the length of the source address.
SRC_offset
is the offset (from the beginning of the M_PROTO message
block) where the source address begins.
OPT_length
is the length the requested options associated with the
primitive.
OPT_offset
is the offset (from the beginning of the M_PROTO message
block) the requested options associated with the
primitive.
The proper alignment of the source address and options in the
M_PROTO message block is not guaranteed.
