std::basic_ios<CharT,Traits>::init - cppreference.com

From cppreference.com

protected:voidinit(std::basic_streambuf<CharT,Traits>*sb);Sets the associated stream buffer to sb and initializes the internal state.

The postconditions are as follows:

Element Value

rdbuf()

sb

tie()

null pointer

rdstate()

goodbit if sb is not a null pointer, otherwise badbit

exceptions()

goodbit

flags()

skipws|dec

width()

0

precision()

6

fill()

widen(' ')

getloc()

a copy of the value returned by std::locale()This member function is protected: it is called by the constructors of the derived stream classes

std::basic_istream

and

std::basic_ostream

once the associated stream buffer is known. Until this function is called, every member function (including the destructor) of the default-constructed

std::basic_ios

invokes undefined behavior. Note that basic_ios is a virtual base class, and therefore its constructor is not called by the constructors of those directly derived classes, which is why two-stage initialization is necessary.

Parameters

sb - stream buffer to associate to See also
