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

loSftp = createobject("CkSFtp")

// Set some timeouts, in milliseconds:
loSftp.ConnectTimeoutMs = 5000
loSftp.IdleTimeoutMs = 10000

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
lcHostname = "sftp.example.com"
lnPort = 22
llSuccess = loSftp.Connect(lcHostname,lnPort)
if (llSuccess <> .T.) then
    ? loSftp.LastErrorText
    release loSftp
    return
endif

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.
llSuccess = loSftp.AuthenticatePw("myLogin","myPassword")
if (llSuccess <> .T.) then
    ? loSftp.LastErrorText
    release loSftp
    return
endif

// After authenticating, the SFTP subsystem must be initialized:
llSuccess = loSftp.InitializeSftp()
if (llSuccess <> .T.) then
    ? loSftp.LastErrorText
    release loSftp
    return
endif

// Download the file:

lcLocalFilePath = "c:/temp/hamlet.xml"
lcRemoteFilePath = "subdir1/subdir2/hamlet.xml"
// The ResumeDownloadFileByName method will check
// the local file and begin downloading the remote file
// at the appropriate point.  For example, if the local
// file is already 215624 bytes long, it will begin downloading
// the remote file at the 215625'th byte -- appending to
// the local file.
llSuccess = loSftp.ResumeDownloadFileByName(lcRemoteFilePath,lcLocalFilePath)
if (llSuccess <> .T.) then
    ? loSftp.LastErrorText
    release loSftp
    return
