- *             _lbfsize is -_bf._size, else _lbfsize is 0
- *     if _flags&__SRD, _w is 0
- *     if _flags&__SWR, _r is 0
- *
- * This ensures that the getc and putc macros (or inline functions) never
- * try to write or read from a file that is in `read' or `write' mode.
- * (Moreover, they can, and do, automatically switch from read mode to
- * write mode, and back, on "r+" and "w+" files.)
- *
- * _lbfsize is used only to make the inline line-buffered output stream
- * code as compact as possible.
- *
- * _ub, _up, and _ur are used when ungetc() pushes back more characters
- * than fit in the current _bf, or when ungetc() pushes back a character
- * that does not match the previous one in _bf.  When this happens,
- * _ub._base becomes non-nil (i.e., a stream has ungetc() data iff
- * _ub._base!=NULL) and _up and _ur save the current values of _p and _r.
- *
- * NB: see WARNING above before changing the layout of this structure!
