basic_streambuf::pbackfail
 
int_type overflow( int_type ch = traits::eof() );
Asegura que hay espacio en el área de poner por lo menos un carácter por el ahorro de algunos subsecuencia inicial de caracteres a partir pbase() a la secuencia de salida y la actualización de los punteros a la zona de salida (si es necesario). Si no es ch traits::eof() (es decir traits::eq_int_type(c, traits::eof()) != true), o bien se ponen a la zona de salida o directamente guarda en la secuencia de salida .
Original:
Ensures that there space at the put area for at least one character by saving some initial subsequence of characters starting at pbase() to the output sequence and updating the pointers to the output area (if needed). If ch is not traits::eof() (i.e. traits::eq_int_type(c, traits::eof()) != true), it is either put to the output area or directly saved to the output sequence.
