NAME

flush - Flush buffered output for a channel

SYNOPSIS

flush channelId _________________________________________________________________

DESCRIPTION

Flushes any output that has been buffered for channelId. ChannelId must be a channel identifier such as returned by a previous open or socket 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.
