std::chrono::operator<<(std::chrono::year_month) (3) - Linux Man Pages

std::chrono::operator<<(std::chrono::year_month): std::chrono::operator<<(std::chrono::year_month)

NAME

std::chrono::operator<<(std::chrono::year_month) - std::chrono::operator<<(std::chrono::year_month)

Synopsis


template< class CharT, class Traits >
std::basic_ostream<CharT, Traits>& (since C++20)
operator<<(std::basic_ostream<CharT, Traits>& os, const std::chrono::year_month& ym);


Outputs a textual representation of ym into the stream os, as if by os << ym.year() << '/' << ym.month().

Return value


os.

Notes


This operator<< is primarily intended for debugging use. When used with non-default stream flags, the output may be surprising:


  using namespace std::chrono;
  auto ym = 2001y/February;
  std::cout.width(10);
  std::cout.fill('-');
  std::cout << std::left << ym; // may output "2001------/Feb"


For control over formatting, use std::chrono::format.
