* If setvbuf(., ., _IONBF, .) is called, bufl is set to 0 and

* If setvbuf(., ., _IOLBF, .) is called, _IO_putc leaves wp and rp pointed at the

* a newline. This nonsense is in order to avoid impacting performance of the other

* According to X3J11, there is only one i/o buffer

* On open, rp, wp and buf are set to 0, so first getc or putc will call _IO_getc

* If setvbuf(., ., _IONBF, .) is called, bufl is set to 0 and
* buf, rp and wp are pointed at unbuf.
* If setvbuf(., ., _IOLBF, .) is called, _IO_putc leaves wp and rp pointed at the
* end of the buffer so that it can be called on each putc to check whether it's got
* a newline. This nonsense is in order to avoid impacting performance of the other
