Class
Foam::errorManip
Description
Error stream manipulators for exit and abort which may terminate the
program or throw an exception depending if the exception
handling has been switched on (off by default).
Usage
\code
error << "message1" << "message2" << FoamDataType << exit(error, errNo);
error << "message1" << "message2" << FoamDataType << abort(error);
\endcode
