13 ?S: This variable conditionally defines the HAS_GETHOSTBYNAME_R symbol,
14 ?S: which indicates to the C program that the gethostbyname_r()
15 ?S: routine is available.
17 ?S:gethostbyname_r_proto:
18 ?S: This variable encodes the prototype of gethostbyname_r.
19 ?S: It is zero if d_gethostbyname_r is undef, and one of the
20 ?S: REENTRANT_PROTO_T_ABC macros of reentr.h if d_gethostbyname_r
23 ?C:HAS_GETHOSTBYNAME_R:
24 ?C: This symbol, if defined, indicates that the gethostbyname_r routine
25 ?C: is available to gethostbyname re-entrantly.
27 ?C:GETHOSTBYNAME_R_PROTO:
28 ?C: This symbol encodes the prototype of gethostbyname_r.
29 ?C: It is zero if d_gethostbyname_r is undef, and one of the
