# NAME
|
|
|
|
libssh2_sftp_fsync - synchronize file to disk
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <libssh2.h>
|
|
#include <libssh2_sftp.h>
|
|
|
|
int libssh2_sftp_fsync(LIBSSH2_SFTP_HANDLE *handle)
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
This function causes the remote server to synchronize the file
|
|
data and metadata to disk (like fsync(2)).
|
|
|
|
For this to work requires fsync@openssh.com support on the server.
|
|
|
|
*handle* - SFTP File Handle as returned by libssh2_sftp_open_ex(3)
|
|
|
|
# RETURN VALUE
|
|
|
|
Returns 0 on success or negative on failure. If used in non-blocking mode, it
|
|
returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
|
|
LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure per se.
|
|
|
|
# ERRORS
|
|
|
|
*LIBSSH2_ERROR_ALLOC* - An internal memory allocation call failed.
|
|
|
|
*LIBSSH2_ERROR_SOCKET_SEND* - Unable to send data on socket.
|
|
|
|
*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. In particular, this can be returned if
|
|
the SSH server does not support the fsync operation: the SFTP subcode
|
|
*LIBSSH2_FX_OP_UNSUPPORTED* is returned in this case.
|
|
|
|
# AVAILABILITY
|
|
|
|
Added in libssh2 1.4.4 and OpenSSH 6.3.
