Calling this method is normally unnecessary, unless you wish to interrupt the remote program, or the remote program is waiting for standard input to end before terminating.
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.)
