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

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

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.

// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.

endif

// Assuming we know the file size won't be too large, we get the size as a 32-bit integer.
// For SFTP, the remote file path is always either a path relative to the HOME directory of the user account, or an absolute path on the server.

// You can convert the string to a 64-bit integer in your programming language.
