12 ?S: This variable conditionally defines the HAS_SRANDOM_R symbol,
13 ?S: which indicates to the C program that the srandom_r()
14 ?S: routine is available.
17 ?S: This variable encodes the prototype of srandom_r.
18 ?S: It is zero if d_srandom_r is undef, and one of the
19 ?S: REENTRANT_PROTO_T_ABC macros of reentr.h if d_srandom_r
23 ?C: This symbol, if defined, indicates that the srandom_r routine
24 ?C: is available to srandom re-entrantly.
27 ?C: This symbol encodes the prototype of srandom_r.
28 ?C: It is zero if d_srandom_r is undef, and one of the
