.SH NAME
.B DL_REPLY_IND (dl_reply_ind_t)
\- this primitive is the service indication primitive for the
acknowledged connectionless-mode data unit exchange service.
.SH DESCRIPTION
This primitive is the service indication primitive for the acknowledged
connectionless-mode data unit exchange service.  It is passed from the DLS
Provider to the DLS User to indicate either asuccessful request of a DLSDU
from the peer data link user entity, or exchange of DLSDUs with a peer data
link user entity.
.SH SYNOPSIS
Consists of one
.B M_PROTO
message block containing the structure shown below, followed by zero or more
.B M_DATA
blocks.

.SH PARAMETERS
.TP
.I dl_primitive
conveys
.BR DL_REPLY_IND .
.TP
.I dl_dest_addr_length
conveys the length of the DLSAP address of the destination DLS User.  If the
destination user is implemented using DLPI, this address is the full DLSAP
address returned on the
.BR DL_BIND_ACK (7).
.TP
.I dl_dest_addr_offset
conveys the offset from the beginning of the
.B M_PROTO
message block where the destination DLSAP address begins.
.TP
.I dl_src_addr_length
conveys the length of the DLSAP address of the source DLS User.
.TP
.I dl_src_addr_offset
conveys the offset from the beginning of the
.B M_PROTO
message block where the source DLSAP address begins.
.TP
.I dl_priority
priority provided for the data unit transmission.
.TP
.I dl_service_class
specifies whether or not an acknowledge capability in the medium access
control sublayer is to be used for the data unit transmission.
.SH STATE
This primitive is valid in state
.BR DL_IDLE .
.SH "NEW STATE"
The resulting state is unchanged.
