NAME
       libssh2_channel_write_ex - write data to a channel stream blocking


SYNOPSIS
       #include <libssh2.h>

       ssize_t
       libssh2_channel_write_ex(LIBSSH2_CHANNEL *channel,
                                int stream_id, char *buf,
                                size_t buflen);


DESCRIPTION
       Write data to a channel stream. All channel streams have one standard I/O substream (stream_id == 0), and
       may  have  up  to  2^32  extended data streams as identified by the selected stream_id. The SSH2 protocol
       currently defines a stream ID of 1 to be the stderr substream.

       channel - active channel stream to write to.

       stream_id - substream ID number (e.g. 0 or SSH_EXTENDED_DATA_STDERR)

       buf - pointer to buffer to write

       buflen - size of the data to write

       libssh2_channel_write(3) and libssh2_channel_write_stderr(3) are convenience macros for this function.

       libssh2_channel_write_ex(3) will use as much as possible of the buffer and  put  it  into  a  single  SSH
       protocol  packet. This means that to get maximum performance when sending larger files, you should try to
       always pass in at least 32K of data to this function.


RETURN VALUE
       Actual number of bytes written or negative on failure.   LIBSSH2_ERROR_EAGAIN  when  it  would  otherwise
       block. While LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure per se.


ERRORS
       LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.

       LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

       LIBSSH2_ERROR_CHANNEL_CLOSED - The channel has been closed.

       LIBSSH2_ERROR_CHANNEL_EOF_SENT - The channel has been requested to be

       LIBSSH2_ERROR_BAD_USE  -  This  can be returned if you ignored a previous return for LIBSSH2_ERROR_EAGAIN
       and rather than sending the original buffer with the  original  size,  you  sent  a  new  buffer  with  a
       different size.

       closed.
