| /* Before including this file, the including file must have included |
| <bits/environments.h> (generally via <unistd.h>) and must have |
| defined the following macros, exactly one of which will be called |
| for each POSIX environment: |
| |
| KNOWN_PRESENT_ENVIRONMENT, for POSIX environments that are known to |
| be supported in this libc. |
| |
| KNOWN_ABSENT_ENVIRONMENT, for POSIX environments that are known not |
| to be supported on this system. |
| |
| UNKNOWN_ENVIRONMENT, for POSIX environments not supported in this |
| libc but possibly supported by another libc on the same system, |
| that can be selected using the same compiler but different |
| compilation options. |
| |
| Each macro has arguments (SC_PREFIX, ENV_PREFIX, SUFFIX). The |
| corresponding argument to sysconf is _SC_##SC_PREFIX##_##SUFFIX. |
| The environment name, as used with getconf, is |
| ENV_PREFIX##_##SUFFIX, and the corresponding macro is the same with |
| a leading "_". |
| |
| In addition, the macros START_ENV_GROUP and END_ENV_GROUP must be |
| defined. These are called with arguments V5, V6, V7 before and |
| after the relevant groups of environments. */ |
