public member type
<ios> <iostream>
Type to indicate event type
Enum type used as the first parameter in functions registered with ios_base::register_callback. This argument identifies the type of event that triggered the function call.
| value | event 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 stream destructor (also called at the beginning of ios::copyfmt). |
| imbue_event | on a call to ios_base::imbue (just before the function returns). |
This member enum type is defined within ios_base as:
1
|
enum event { erase_event, imbue_event, copyfmt_event };
