count caracteres da seqüência de entrada e armazena-os em uma matriz de caracteres apontada por s. Os caracteres são lidos como se por chamadas repetidas para sbumpc(). Ou seja, se menos de personagens count estão imediatamente disponíveis, a função chama uflow() para fornecer mais até traits::eof() é devolvido.
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.
