libssh2_sftp_fsync(3) libssh2 manual libssh2_sftp_fsync(3)
NAME
libssh2_sftp_fsync - synchronize file to disk
SYNOPSIS
#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 isn't 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 LIB-
SSH2_FX_OP_UNSUPPORTED will be returned in this case.
AVAILABILITY
Added in libssh2 1.4.4 and OpenSSH 6.3.
