|
* 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.
