NAME

6       nbdkit-exitlast-filter - exit on last client connection
7

SYNOPSIS

9        nbdkit --filter=exitlast PLUGIN
10

DESCRIPTION

12       "nbdkit-exitlast-filter" is an nbdkit filter that causes nbdkit to exit
13       when there are no more client connections.  Note that it doesn't exit
14       before the first client connection.
15
16       One use for this is in combination with a superserver, to save
17       resources when nbdkit is not in use (see nbdkit-service(1)).  Another
18       use is to ensure nbdkit exits after the client has finished (but see
19       also nbdkit-captive(1) for other ways to do this).
20
21       To exit when an event occurs, try nbdkit-exitwhen-filter(1).
22
