operator<<(std::basic_ostream)

 

basic_ostream& write( const char_type* s, std::streamsize count );

Outputs characters from successive locations in the character array whose first element is pointed to by s. Characters are inserted into the output sequence until one of the following occurs:

• exactly count characters are inserted
• inserting into the output sequence fails (in which case setstate(badbit) is called)

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)

Also, unlike the formatted output functions, this function does not set the failbit on failure.

Исключения

If an exception occurs during output and exceptions()&badbit != 0, rethrows that exception.

If output fails and exceptions()&badbit != 0, throws ios_base::failure.

Пример

This function may be used to output object representations, i.e. binary output

#include <iostream>
int main()
{
    int n = 0x41424344;
    std::cout.write(reinterpret_cast<char*>(&n), sizeof n);
    std::cout << '\n';
}
