.SH DESCRIPTION
.sp
.LP
The \fBenableok()\fR function enables queue \fIq\fR to be rescheduled for
service. It reverses the effect of a previous call to \fBnoenable\fR(9F) on
\fIq\fR by turning off the \fBQNOENB\fR flag in the queue.
.SH CONTEXT
.sp
.LP
The \fBenableok()\fR function can be called from user, interrupt, or kernel
context.
.SH EXAMPLES
.LP
\fBExample 1 \fRUsing \fBemableok()\fR
.sp
.LP
The \fBqrestart()\fR routine uses two STREAMS functions to restart a queue that
has been disabled. The \fBenableok()\fR function turns off the  \fBQNOENB\fR
flag, allowing the \fBqenable\fR(9F) to schedule the queue for immediate
processing.
