libssh2_sftp_fsync(3)               libssh2              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 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 will be returned in this case.


AVAILABILITY

       Added in libssh2 1.4.4 and OpenSSH 6.3.
