Once the error handler is called the calling function is then returned from with the given error code.

There are also versions for 4, 5, 6 and 7 arguments.

Experienced users can set the error handler with <A HREF="../Sys/PetscPushErrorHandler.html#PetscPushErrorHandler">PetscPushErrorHandler</A>().
