Ping Method
Sends a keep-alive request to the SSH server.
Syntax
int Ping();
Remarks
Use this method to send a keep-alive message to the SSH server. Keep-alive messages are empty data packets which carry no useful information but are a handy way of checking if the connection is still alive.
Error Handling
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
