void
unexpected
();
The function calls the current unexpected handler, a function of type void ()
called when control leaves a function
by a thrown exception of a type not permitted by an exception specification for the function, as in:
void f() throw() // function may throw no exceptions
{throw "bad"; } // unexpected throw calls unexpected()
An unexpected handler may not return to its caller. It may terminate execution by:
bad_exception
. terminate
()
, abort
()
, or exit
(int)
. At program startup, the unexpected handler is a function that calls terminate
()
.
