示例1: insert_fill_chars
inline void insert_fill_chars(std::basic_ostream<charT, traits>& os, std::size_t n) {
enum { chunk_size = 8 };
charT fill_chars[chunk_size];
std::fill_n(fill_chars, static_cast< std::size_t >(chunk_size), os.fill());
for (; n >= chunk_size && os.good(); n -= chunk_size)
os.write(fill_chars, static_cast< std::size_t >(chunk_size));
if (n > 0 && os.good())
os.write(fill_chars, n);

void write(const CharT* s, size_t length)
{
size_t diff = end_buffer_ - p_;
if (diff >= length)
{
std::memcpy(p_, s, length*sizeof(CharT));
p_ += length;
}
else
{
os_->write(begin_buffer_, (p_ - begin_buffer_));
os_->write(s, length);
p_ = begin_buffer_;
}
