-Subject: [PATCH 3/3] sftp: Add support for fsync (OpenSSH extension).
-
-The new libssh2_sftp_fsync API causes data and metadata in the
-currently open file to be committed to disk at the server.
-
-This is an OpenSSH extension to the SFTP protocol. See:

-+.TH libssh2_sftp_fsync 3 "8 Apr 2013" "libssh2 1.4.4" "libssh2 manual"
-+.SH NAME
-+libssh2_sftp_fsync - synchronize file to disk
-+.SH SYNOPSIS
-+.nf
-+#include <libssh2.h>
-+#include <libssh2_sftp.h>
-+
-+int
-+libssh2_sftp_fsync(LIBSSH2_SFTP_HANDLE *handle)
-+.fi
-+.SH 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.
-+
-+\fIhandle\fP - SFTP File Handle as returned by
-+.BR libssh2_sftp_open_ex(3)
-+
-+.SH 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.
-+.SH ERRORS
-+\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.
-+
-+\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
-+
-+\fILIBSSH2_ERROR_SFTP_PROTOCOL\fP - 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
-+\fILIBSSH2_FX_OP_UNSUPPORTED\fP will be returned in this case.
-+
-+.SH AVAILABILITY
-+Added in libssh2 1.4.4 and OpenSSH 6.3.
-+.SH SEE ALSO
-+.BR fsync(2)
