.SH DESCRIPTION
All functions described in this manpage take a pointer to the message passed to
the \fBDLPI\fR provider (\fBmblk_t\fR) and attempt to reuse it in formulating
the \fBM_PROTO\fR reply. If the message block is too small to be reused, it is
freed and a new one is allocated.
.sp
.LP
All functions reply upstream using \fBqreply\fR(9F). The write-side queue
pointer must be provided.
.sp
.LP
The \fBdlokack()\fR function provides the successful acknowledgement
\fBDL_OK_ACK\fR message reply to the \fBDLPI\fR provider and is used to
complete many of the \fBDLPI\fR requests in the \fBDLPI\fR consumer.
.sp
.LP
The \fBdlerrorack()\fR function provides the unsuccessful acknowledgement
\fBDL_ERROR_ACK\fR message reply to the \fBDLPI\fR() provider and is used for
error completions were required for \fBDLPI\fR requests in the \fBDLPI\fR
consumer.
.sp
.LP
The \fBdlbindack()\fR function provides the \fBDL_BIND_ACK\fR message reply to
the \fBDLPI\fR provider and is used to complete the \fBDL_BIND_REQ\fR
processing in the \fBDLPI\fR consumer.
.sp
.LP
The \fBdlphysaddrack()\fR function provides the \fB\fR()\fBDL_PHYS_ADDR_ACK\fR
message reply used to complete the \fBDL_PHYS_ADDR_ACK\fR processing.
.sp
.LP
The \fBdluderrorind()\fR function provides the \fBDL_UDERROR_IND\fR message
reply used to complete an unsuccessful \fBDL_UNITDATA_REQ\fR.
.SH RETURN VALUES
None.
.SH NOTES
These functions are not required if you are are writing a \fBDLPI\fR device
driver using \fBgld\fR(4D).
.SH CONTEXT
All \fBDLPI\fR helper functions can be called from user, interrupt, or kernel
context.
