.SH NAME
|
|
libssh2_channel_write_ex - write data to a channel stream blocking
|
|
.SH SYNOPSIS
|
|
#include <libssh2.h>
|
|
|
|
size_t libssh2_channel_write_ex(LIBSSH2_CHANNEL *channel, int stream_id,
|
|
char *buf, size_t buflen);
|
|
|
|
size_t libssh2_channel_write(LIBSSH2_CHANNEL *channel, char *buf,
|
|
size_t buflen);
|
|
|
|
size_t libssh2_channel_write_stderr(LIBSSH2_CHANNEL *channel, char *buf,
|
|
size_t buflen);
|
|
.SH 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 \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
|
|
macros.
|
|
.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.
