Esta función es una función de salida sin formato: se inicia la ejecución mediante la construcción de un objeto de tipo
sentry, que vacía los buffers de salida tie()'d si es necesario y comprueba los errores de secuencia. Después de la construcción, si se devuelve el objeto centinela false, la función devuelve sin pretender ninguna salida. Si se produce una excepción durante la salida, entonces ios :: badbit se establece (se suprime la excepción a menos que exceptions()&badbit) != 0, en cuyo caso se vuelve a iniciar)Original:

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.
