`class ErrorException`

This exception is thrown by calls to the error function. Typical code for catching errors looks like this:

   try {
      ... code in which an error might occur ...
   } catch (ErrorException& ex) {
      ... code to handle the error condition ...
   }

If an ErrorException is thrown at any point in the range of the try (including in functions called from that code), control will jump immediately to the error handler.

Function
error(`msg`)	Signals an error condition in a program by throwing an `ErrorException` with the specified message.
