.SH NAME
libssh2_session_startup - begin transport layer
.SH SYNOPSIS
#include <libssh2.h>

int 
libssh2_session_startup(LIBSSH2_SESSION *session, int socket);
.SH DESCRIPTION
Starting in libssh2 version 1.2.8 this function is considered deprecated. Use
\fIlibssh2_session_handshake(3)\fP instead.

\fIsession\fP - Session instance as returned by 
.BR libssh2_session_init_ex(3)

\fIsocket\fP - Connected socket descriptor. Typically a TCP connection 
though the protocol allows for any reliable transport and the library will 
attempt to use any berkeley socket.

Begin transport layer protocol negotiation with the connected host.
.SH RETURN VALUE
Returns 0 on success, negative on failure.
.SH ERRORS
\fILIBSSH2_ERROR_SOCKET_NONE\fP - The socket is invalid.

\fILIBSSH2_ERROR_BANNER_SEND\fP - Unable to send banner to remote host.

\fILIBSSH2_ERROR_KEX_FAILURE\fP - >Encryption key exchange with the remote 
host failed.

\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.

\fILIBSSH2_ERROR_SOCKET_DISCONNECT\fP - The socket was disconnected.

\fILIBSSH2_ERROR_PROTO\fP - An invalid SSH protocol response was received on 
the socket.

\fILIBSSH2_ERROR_EAGAIN\fP - Marked for non-blocking I/O but the call would block.

libssh2_session_handshake: replaces libssh2_session_startup() The function libssh2_session_startup() is now considered deprecated due to the portability issue with the socket argument. libssh2_session_handshake() is the name of the replacement. 2010-10-07 19:51:28 +02:00			`Starting in libssh2 version 1.2.8 this function is considered deprecated.

Modify the code to truely support non-blocking. Propogate the EAGAIN error all the way up to the user interface. All code modules bug sftp.c have been completed. Functions that return an "int", or similar return LIBSSH2CHANNEL_EAGAIN to indicate some part of the call would block, in non-blocking mode. Functions that return a structure, like "LIBSSH2_CHANNEL *", return NULL and set the libssh2 error. The error can be obtained with either libssh2_session_last_error() or libssh2_session_last_errno(). Either of these will return the error code of LIBSSH2_ERROR_EAGAIN if the call would block, in non-blocking mode. The current state of a function and some variable are keep in the structures so that on the next call the operation that would block can be retried again with the same data. 2007-06-06 14:34:06 +02:00			`.SH ERRORS`
