+
+// This file provides a low-level interface between the internal
+// representation of struct FILE, from the C stdio library, and
+// the C++ I/O library.  The C++ I/O library views a FILE object as
+// a collection of three pointers: the beginning of the buffer, the
+// current read/write position, and the end of the buffer.
+
+// The interface:
+// - char* _FILE_[IO]_begin(const FILE *__f);
+//       Returns a pointer to the beginning of the buffer.
+// - char* _FILE_[IO]_next(const FILE *__f);
+//       Returns the current read/write position within the buffer.
+// - char* _FILE_[IO]_end(const FILE *__f);
+//       Returns a pointer immediately past the end of the buffer.
+// - char* _FILE_[IO]_avail(const FILE *__f);
+//       Returns the number of characters remaining in the buffer, i.e.
+//       _FILE_[IO]_end(__f) - _FILE_[IO]_next(__f).
+// - char& _FILE_[IO]_preincr(FILE *__f)
+//       Increments the current read/write position by 1, returning the
+//       character at the old position.
+// - char& _FILE_[IO]_postincr(FILE *__f)
+//       Increments the current read/write position by 1, returning the
+//       character at the old position.
+// - char& _FILE_[IO]_predecr(FILE *__f)
+//       Decrements the current read/write position by 1, returning the
+//       character at the old position.
+// - char& _FILE_[IO]_postdecr(FILE *__f)
+//       Decrements the current read/write position by 1, returning the
+//       character at the old position.
+// - void _FILE_[IO]_bump(FILE *__f, int __n)
+//       Increments the current read/write position by __n.
+// - void _FILE_[IO]_set(FILE *__f, char* __begin, char* __next, char* __end);
+//       Sets the beginning of the bufer to __begin, the current read/write
+//       position to __next, and the buffer's past-the-end pointer to __end.
+//       If any of those pointers is null, then all of them must be null.
+
+// Each function comes in two versions, one for a FILE used as an input
+// buffer and one for a FILE used as an output buffer.  In some stdio
+// implementations the two functions are identical, but in others they are
+// not.
