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
countcharacters are inserted - inserting into the output sequence fails (in which case
setstate(badbit)is called)
Esta função é uma função de saída não formatada: ela iniciar a execução através da construção de um objeto de
sentry tipo, o que esvazia os buffers de saída tie()'d se necessário e verifica os erros de fluxo. Após a construção, se os retornos de sentinela objeto false, a função retorna sem tentar qualquer saída. Se uma exceção é lançada durante a saída, então ios :: badbit está definido (a exceção é suprimida a menos exceptions()&badbit != 0, caso em que é relançada)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)The text has been machine-translated via Google Translate.

Also, unlike the formatted output functions, this function does not set the failbit on failure.
Exceções
If an exception occurs during output and exceptions()&badbit != 0, rethrows that exception.
If output fails and exceptions()&badbit != 0, throws ios_base::failure.
Exemplo
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';
}
