Checks whether an error requires re-connection.
Defined in header <boost/mysql/is_fatal_error.hpp>
bool is_fatal_error( error_code ec);
After an operation on an established connection (like executing a query) fails, the connection may be usable for further operations (if the error was non-fatal) or not (if the error was fatal). This function determines whether an error code returned by a connection operation is fatal or not.
To recover from a fatal error code, close and re-establish the connection.
No-throw guarantee.
