NAME¶

std::setiosflags - std::setiosflags

Synopsis¶

Defined in header <iomanip>
/*unspecified*/ setiosflags( std::ios_base::fmtflags 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.

Parameters¶

mask - bitmask of the flags to set

Return value¶

Returns an object of unspecified type such that if str is the name of a 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¶

// Run this code

#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
