Эта функция является функцией неформатированный выход: она начала выполнения с помощью построения объекта типа sentry, который очищает tie()'d выходные буферы при необходимости и проверяет поток ошибок. После завершения строительных работ, если часовой объект возвращается false, функция возвращает не пытаясь никаких выходных данных. Если исключение во время выходных, то IOS :: badbit установлен (за исключением подавляется, если exceptions()&badbit) != 0, в этом случае он выдается повторно)

Original:

This function is an unformatted output function: it begin execution by constructing an object of type sentry, which flushes the tie()'d output buffers if necessary and checks the stream errors. After construction, if the sentry object returns false, the function returns without attempting any output. If an exception is thrown during output, then ios::badbit is set (the exception is suppressed unless exceptions()&badbit) != 0, in which case it is rethrown)

Пример

#include <fstream>
#include <iostream>
int main()
{
    std::cout.put('a'); // normal usage
    std::cout.put('\n');
 
    std::ofstream s("/does/not/exist/");
    s.clear(); // pretend the stream is good
    std::cout << "Unformatted output: ";
    s.put('c'); // this will set badbit, but not failbit
    std::cout << " fail=" << bool(s.rdstate() & s.failbit);
    std::cout << " bad=" << s.bad() << '\n';
    s.clear();
    std::cout << "Formatted output:   ";
    s << 'c'; // this will set badbit and failbit
    std::cout << " fail=" << bool(s.rdstate() & s.failbit);
    std::cout << " bad=" << s.bad() << '\n';
}

Вывод:

a
Unformatted output:  fail=0 bad=1
Formatted output:    fail=1 bad=1
