SFTP Fsync -- Flush an Open File on the Server

See more SFTP Examples

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. Lua

local chilkat = require("chilkat")

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

local sftp = chilkat.SFtp.new()

-- Pass a domain or IP address..
local success = sftp:connect("my-sftp-server.com", 22)
if success then
    success = sftp:authenticate_pw("mySFtpLogin", "mySFtpPassword")
end

if success then
    success = sftp:initialize_sftp()
end

if not success then
    print(sftp.last_error_text)
    return
end

-- Open a file on the server for writing.
local handle = sftp:open_file("myTest.txt", "writeOnly", "createTruncate")
if not sftp.last_method_success then
    print(sftp.last_error_text)
    return
end

-- Write some text to the file:
success = sftp:write_file_text(handle, "ansi", "abcdefghijklmnopqrstuvwxyz")
if not success then
    print(sftp.last_error_text)
    return
end

-- 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 not success then
    print(sftp.last_error_text)
    return
end

-- ....
-- ....

success = sftp:write_file_text(handle, "ansi", "ABCDEFGHIJKLMNOPQRSTUVWXYZ")
if not success then
    print(sftp.last_error_text)
    return
end

-- Close the file.
success = sftp:close_handle(handle)
if not success then
    print(sftp.last_error_text)
    return
end

print("Success.")
