21 Write data to a channel stream. All channel streams have one standard
22 I/O substream (stream_id == 0), and may have up to 2^32 extended data
23 streams as identified by the selected stream_id. The SSH2 protocol cur‐
24 rently defines a stream ID of 1 to be the stderr substream.
25
26 channel - active channel stream to write to.
27
28 stream_id - substream ID number (e.g. 0 or SSH_EXTENDED_DATA_STDERR)
29
30 buf - pointer to buffer to write
31
32 buflen - size of the data to write

38 Actual number of bytes written or negative on failure. LIB‐
39 SSH2_ERROR_EAGAIN when it would otherwise block. While LIB‐
40 SSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per
41 se.
42
44 LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.
45
46 LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
47
48 LIBSSH2_ERROR_CHANNEL_CLOSED - The channel has been closed.
49
50 LIBSSH2_ERROR_CHANNEL_EOF_SENT - The channel has been requested to be
51 closed.
