12 ?S: This variable conditionally defines the HAS_TTYNAME_R symbol,
13 ?S: which indicates to the C program that the ttyname_r()
14 ?S: routine is available.
17 ?S: This variable encodes the prototype of ttyname_r.
20 ?C: This symbol, if defined, indicates that the ttyname_r routine
21 ?C: is available to ttyname re-entrantly.
24 ?C: This symbol encodes the prototype of ttyname_r.
