T_DISCON_IND --
Disconnect Indication
Synopsis
This message consists of a M_PROTO message block
formatted as follows:
struct T_discon_ind {
long PRIM_type; /* always T_DISCON_IND */
long DISCON_reason; /* disconnect reason - */
long SEQ_number; /* sequence number - */
}
Description
This primitive indicates to the user that either a request for connection
has been denied or an existing connection has been disconnected.
The format of this message is one M_PROTO message block possibly followed by
one or more M_DATA message blocks if there is any user data
associated with the primitive.
Parameters
PRIM_type-
identifies the primitive type
DISCON_reason-
is the reason for disconnect.
The reason codes are protocol specific.
SEQ_number-
is the sequence number which identifies
which connect indication was denied, or it is -1 if the provider
is disconnecting
an existing connection.
Rules
The SEQ_number
is only meaningful when this primitive is sent to a passive user
who has the corresponding connect indication outstanding.
It allows the transport user to identify which of its outstanding
connect indications is associated with the disconnect.
Modes
Only connection-mode.
Originator
