std::basic_ios::copyfmt

From cppreference.com
basic_ios& copyfmt(const basic_ios& other);

Copies the formatting flags from stream other. This is done in the following sequence:

1) Calls callbacks, registered by register_callback() passing erase_event as parameter

2) Copies the formatting information from other to *this. Internal data array is also copied. rdstate() is left unchanged.

3) Calls callbacks, registered by register_callback() passing copyfmt_event as parameter

4) Copies the exception mask from other to *this.

Sets the stream error flags state in addition to currently set flags. Essentially calls clear(rdstate() | state). May throw an exception.
