19/* Before including this file, the including file must have included
20 <bits/environments.h> (generally via <unistd.h>) and must have
21 defined the following macros, exactly one of which will be called
22 for each POSIX environment:
23
24 KNOWN_PRESENT_ENVIRONMENT, for POSIX environments that are known to
25 be supported in this libc.
26
27 KNOWN_ABSENT_ENVIRONMENT, for POSIX environments that are known not
28 to be supported on this system.
29
30 UNKNOWN_ENVIRONMENT, for POSIX environments not supported in this
31 libc but possibly supported by another libc on the same system,
32 that can be selected using the same compiler but different
33 compilation options.
34
35 Each macro has arguments (SC_PREFIX, ENV_PREFIX, SUFFIX). The
36 corresponding argument to sysconf is _SC_##SC_PREFIX##_##SUFFIX.
37 The environment name, as used with getconf, is
38 ENV_PREFIX##_##SUFFIX, and the corresponding macro is the same with
39 a leading "_".
40
41 In addition, the macros START_ENV_GROUP and END_ENV_GROUP must be
42 defined. These are called with arguments V5, V6, V7 before and
43 after the relevant groups of environments. */
