Defined in header <iomanip>
/*unspecified*/ setiosflags( std::ios_base::fmt_flags mask );

When used in an expression out << setiosflags(mask) or in >> setiosflags(mask), sets all format flags of the stream out or in as specified by the mask.

Contents

Parameters

mask - bitmask of the flags to set

Return value

Returns an object of unspecified type such that if str is the name of an output stream of type std::basic_ostream<CharT, Traits> or std::basic_istream<CharT, Traits>, then the expression str << setiosflags(mask) or str >> setiosflags(mask) behaves as if the following code was executed:

str.setf(mask);

Example

#include <iostream>
#include <iomanip>
 
int main()
{
    std::cout <<  std::resetiosflags(std::ios_base::dec) 
              <<  std::setiosflags(  std::ios_base::hex
                                   | std::ios_base::uppercase
                                   | std::ios_base::showbase) << 42 << '\n';
}

Output:

0X2A
