The variables that can be queried using sysconf.

Each variable corresponds to a sysconf variable defined by POSIX. For example, ScArgMax corresponds to the _SC_ARG_MAX variable, and so on.

Different variables may have been added at different times, and as a result, some variables may not be supported on older systems. In these cases, sysconf will return an error.
