Please help on print string that contains 'tab' and 'newline'

[Jason Qian]

Thanks for taking look this.

1. Python pass a function to c side as callback, and print out the message.

def handleError(message, code):
 print('** handleError **')
* print('exception ' + str(message))*

2. On c side : send stack trace back to python by calling the callback
function

Callback::Callback(InvocationER rcb)
:
_rcb(rcb)
{
}
void Callback::handleError(Exception &e, int taskId) {
 *(_rcb)((char*)e.getStackTrace().c_str(), taskId);*
}


So, the source of the string is std::string. On the python side is byte
array.

      Ljava.lang.Object; does not exist*\r\n\t*at com

Thanks
