basic_ios::copyfmt
basic_ios::copyfmt
basic_ios& copyfmt(const basic_ios& rhs);
The member function reports the callback eventerase_event
. It then copies the fill character, the tie pointer, and the formatting information from rhs
into *this
. Before altering the exception mask, it reports the callback event copyfmt_event
. If, after the copy is complete, state &
exceptions
()
is nonzero, the function effectively calls clear
with the argument rdstate
()
. It returns *this
.
