23 * NOTE 1:
24 * -------
25 *
26 * Nothing in this file is intended to be modified or adjusted by the
27 * c-ares library user nor by the c-ares library builder.
28 *
29 * If you think that something actually needs to be changed, adjusted
30 * or fixed in this file, then, report it on the c-ares development
31 * mailing list: http://cool.haxx.se/mailman/listinfo/c-ares/
32 *
33 * This header file shall only export symbols which are 'cares' or 'CARES'
34 * prefixed, otherwise public name space would be polluted.
35 *
36 * NOTE 2:
37 * -------
38 *
39 * Right now you might be staring at file ares_build.h.in or ares_build.h,
40 * this is due to the following reason:
41 *
42 * On systems capable of running the configure script, the configure process
43 * will overwrite the distributed ares_build.h file with one that is suitable
44 * and specific to the library being configured and built, which is generated
45 * from the ares_build.h.in template file.
46 *
