.SH NAME

flush \- Flush buffered output for a channel
|

|
|
.SH SYNOPSIS
|
||
|
|
\fBflush \fIchannelId\fR
|
||
|
|
.BE
|
||
|
|
|

|
|
.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
Flushes any output that has been buffered for \fIchannelId\fR.
|
||
|
|
\fIChannelId\fR must be a channel identifier such as returned by a previous
|
||
|
|
\fBopen\fR or \fBsocket\fR command, and it must have been opened for writing.
|
||
|
|
If the channel is in blocking mode the command does not return until all the
|
||
|
|
buffered output has been flushed to the channel. If the channel is in
|
||
|
|
nonblocking mode, the command may return before all buffered output has been
|
||
|
|
flushed; the remainder will be flushed in the background as fast as the
|
||
|
|
underlying file or device is able to absorb it.
