Lee count caracteres de la secuencia de entrada y los almacena en una cadena de caracteres apuntada por s. Los caracteres se leen como por los repetidos llamamientos a sbumpc(). Es decir, si menos de caracteres count están inmediatamente disponibles, la función llama uflow() para proporcionar más hasta que se devuelve traits::eof() .
Original:
Reads count characters from the input sequence and stores them into a character array pointed to by s. The characters are read as if by repeated calls to sbumpc(). That is, if less than count characters are immediately available, the function calls uflow() to provide more until traits::eof() is returned.
