43// This version of basic_stringbuf relies on the internal details of
44// basic_string. It relies on the fact that, in this implementation,
45// basic_string's iterators are pointers. It also assumes (as allowed
46// by the standard) that _CharT is a POD type.
47
48// We have a very small buffer for the put area, just so that we don't
49// have to use append() for every sputc. Conceptually, the buffer
50// immediately follows the end of the underlying string. We use this
51// buffer when appending to write-only streambufs, but we don't use it
52// for read-write streambufs.
