Synopsis:
flush
Description:
This discards any data pending in the client's hold buffer when HOLD_MODE
is on (and HOLD_MODE is then turned off). This includes server messages,
and messages generated internally by the client (such as by NOTIFY ). The
client then discards all server messages received, until one full second
passes without receiving anything from the server. It is most useful for
flushing server output from commands that generate a lengthy reply, such
as LINKS or LIST or WHO .
See Also:
set (4) hold_mode
Other Notes:
FLUSH is a blocking command (meaning the client can't do anything until
the command is done), so it may cause the client to ping timeout from
your server. It does not actually tell the server to stop sending data.
