SYNOPSIS

       #include <libssh2.h>

       int
       libssh2_channel_flush_ex(LIBSSH2_CHANNEL *channel, int streamid);

       int
       libssh2_channel_flush(LIBSSH2_CHANNEL *channel);

       int
       libssh2_channel_flush_stderr(LIBSSH2_CHANNEL *channel);

DESCRIPTION

       channel - Active channel stream to flush.

       streamid  -  Specific  substream  number  to flush. Groups of substreams may be flushed by
       passing on of the following Constants.
       LIBSSH2_CHANNEL_FLUSH_EXTENDED_DATA: Flush all extended data substreams
       LIBSSH2_CHANNEL_FLUSH_ALL: Flush all substreams

       Flush the read buffer for a given channel instance. Individual substreams may  be  flushed
       by number or using one of the provided macros.

RETURN VALUE

       Return   the   number   of   bytes   flushed   or   negative   on   failure.   It  returns
       LIBSSH2_ERROR_EAGAIN when it  would  otherwise  block.  While  LIBSSH2_ERROR_EAGAIN  is  a
       negative number, it is not really a failure per se.
