-.SH NAME
-libssh2_channel_read_ex - read data from a channel stream
-.SH SYNOPSIS
-#include <libssh2.h>
-
-int libssh2_channel_readnb_ex(LIBSSH2_CHANNEL *channel, int stream_id,
-                            char *buf, size_t buflen);
-
-int libssh2_channel_readnb(LIBSSH2_CHANNEL *channel, char *buf,
-                         size_t buflen);
-
-int libssh2_channel_readnb_stderr(LIBSSH2_CHANNEL *channel, char *buf,
-                                size_t buflen);
-.SH DESCRIPTION
-Attempt to read data from an active 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 read from. 
-
-\fIstream_id\fP - substream ID number (e.g. 0 or SSH_EXTENDED_DATA_STDERR) 
-
-\fIbuf\fP - pointer to storage buffer to read data into
-
-\fIbuflen\fP - size of the buf storage
-
-\fIlibssh2_channel_read(3)\fP and \fIlibssh2_channel_read_stderr(3)\fP are
-macros.
-.SH RETURN VALUE
-Actual number of bytes read 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.
