(.NET Core C#) SFTP Fsync -- Flush an Open File on the ServerDemonstrates 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. Chilkat.SFtp sftp = new Chilkat.SFtp(); // Pass a domain or IP address.. bool 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) { Debug.WriteLine(sftp.LastErrorText); return; } // Open a file on the server for writing. string handle = sftp.OpenFile("myTest.txt","writeOnly","createTruncate"); if (sftp.LastMethodSuccess != true) { Debug.WriteLine(sftp.LastErrorText); return; } // Write some text to the file: success = sftp.WriteFileText(handle,"ansi","abcdefghijklmnopqrstuvwxyz"); if (success != true) { Debug.WriteLine(sftp.LastErrorText); 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) success = sftp.Fsync(handle); if (success != true) { Debug.WriteLine(sftp.LastErrorText); return; } // .... // .... success = sftp.WriteFileText(handle,"ansi","ABCDEFGHIJKLMNOPQRSTUVWXYZ"); if (success != true) { Debug.WriteLine(sftp.LastErrorText); return; } // Close the file. success = sftp.CloseHandle(handle); if (success != true) { Debug.WriteLine(sftp.LastErrorText); return; } Debug.WriteLine("Success."); |
