#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);
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 0 on success or negative on failure. It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per se.
