The native methods doall the work and return error codes, a return value >= 0 means thecall was successful. The Java methods call the native methods,check the error codes and raise exceptions if errors occured. If the native method get_error_message returns a string that can beused to explain the error to the user.<p><hr><a name="index"></a><h2> <img src="images/variable-index.gif" width=207 height=38
