<ios>
enum event;
Type to indicate event type
Enum type used as the first parameter in functions registered with register_callback. This argument identifies the type of event occured to trigger the function call.

valueevent triggered
copyfmt_event on a call to ios::copyfmt (at the moment where all format flags have been copied, but before the exception mask is)
erase_event on a call to the destructor (also called by at the beginning of ios::copyfmt).
imbue_event on a call to imbue (just before the function returns).

This member enum type is defined within ios_base as:
 
enum event { erase_event, imbue_event, copyfmt_event };
