.SH NAME
nbdkit\-exitlast\-filter \- exit on last client connection
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& nbdkit \-\-filter=exitlast PLUGIN
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\f(CW\*(C`nbdkit\-exitlast\-filter\*(C'\fR is an nbdkit filter that causes nbdkit to
exit when there are no more client connections.  Note that it doesn't
exit before the first client connection.
.PP
One use for this is in combination with a superserver, to save
resources when nbdkit is not in use (see \fBnbdkit\-service\fR\|(1)).
Another use is to ensure nbdkit exits after the client has finished
(but see also \fBnbdkit\-captive\fR\|(1) for other ways to do this).
.PP
To exit when an event occurs, try \fBnbdkit\-exitwhen\-filter\fR\|(1).
.SH PARAMETERS
.IX Header "PARAMETERS"
There are no parameters specific to nbdkit-exitlast-filter.  Any
parameters are passed through to and processed by the underlying
plugin in the normal way.
