(Go) SFTP Fsync -- Flush an Open File on the Server

Demonstrates how to flush the contents of an open file on the server. This example only works for servers that implement the fsync@openssh.com extension.

Note: This example requires Chilkat v9.5.0.71 or later.

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    sftp := chilkat.NewSFtp()

    // Pass a domain or IP address..
    success := sftp.Connect("my-sftp-server.com",22)
    if success == true {
        success = sftp.AuthenticatePw("mySFtpLogin","mySFtpPassword")
    }

    if success == true {
        success = sftp.InitializeSftp()
    }

    if success != true {
        fmt.Println(sftp.LastErrorText())
        sftp.DisposeSFtp()
        return
    }

    // Open a file on the server for writing.
    handle := sftp.OpenFile("myTest.txt","writeOnly","createTruncate")

    if success != true {
        fmt.Println(sftp.LastErrorText())
        sftp.DisposeSFtp()
        return

    // Make sure the server flushes what we wrote to the disk..
    // (this is requires a server that implements the fsync@openssh.com SFTP protocol extension)
