# NAME
|
|
|
|
libssh2_sftp_init - open SFTP channel for the given SSH session.
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <libssh2.h>
|
|
#include <libssh2_sftp.h>
|
|
|
|
LIBSSH2_SFTP *libssh2_sftp_init(LIBSSH2_SESSION *session);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
*session* - Session instance as returned by libssh2_session_init_ex(3)
|
|
|
|
Open a channel and initialize the SFTP subsystem. Although the SFTP subsystem
|
|
operates over the same type of channel as those exported by the Channel API,
|
|
the protocol itself implements its own unique binary packet protocol which
|
|
must be managed with the libssh2_sftp_*() family of functions. When an SFTP
|
|
session is complete, it must be destroyed using the libssh2_sftp_shutdown(3)
|
|
function.
|
|
|
|
# RETURN VALUE
|
|
|
|
A pointer to the newly allocated SFTP instance or NULL on failure.
|
|
|
|
# ERRORS
|
|
|
|
*LIBSSH2_ERROR_ALLOC* - An internal memory allocation call failed.
|
|
|
|
*LIBSSH2_ERROR_SOCKET_SEND* - Unable to send data on socket.
|
|
|
|
*LIBSSH2_ERROR_SOCKET_TIMEOUT* -
|
|
|
|
*LIBSSH2_ERROR_SFTP_PROTOCOL* - An invalid SFTP protocol response was
|
|
received on the socket, or an SFTP operation caused an errorcode to be
|
|
returned by the server.
|
|
|
|
*LIBSSH2_ERROR_EAGAIN* - Marked for non-blocking I/O but the call would
|
|
block.
