Get a list of buffers that represents the output sequence, with the given size.
mutable_buffers_type prepare(
std::size_t n);
Ensures that the output sequence can accommodate n characters,
reallocating character array objects as necessary.
An object of type mutable_buffers_type that satisfies MutableBufferSequence
requirements, representing character array objects at the start of the
output sequence such that the sum of the buffer sizes is n.
If size() + n > max_size().
The returned object is invalidated by any basic_streambuf
member function that modifies the input sequence or output sequence.
