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 \fIstream_id\fP. The SSH2 protocol currently +defines a stream ID of 1 to be the stderr substream. + +\fIchannel\fP - active channel stream to write to. + +\fIstream_id\fP - substream ID number (e.g. 0 or SSH_EXTENDED_DATA_STDERR) + +\fIbuf\fP - pointer to buffer to write + +\fIbuflen\fP - size of the data to write + +\fIlibssh2_channel_write(3)\fP and \fIlibssh2_channel_write_stderr(3)\fP are +convenience macros for this function. + +\fIlibssh2_channel_write_ex(3)\fP 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. +.SH 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 isn't really a failure per se. +.SH ERRORS +\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed. + +\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket. + +\fILIBSSH2_ERROR_CHANNEL_CLOSED\fP - The channel has been closed. + +\fILIBSSH2_ERROR_CHANNEL_EOF_SENT\fP - The channel has been requested to be +closed. +.SH SEE ALSO +.BR libssh2_channel_open_ex(3) +.BR libssh2_channel_read_ex(3) |
