<p>Nix uses the same naming convention for these variables as the

<a href="http://pubs.opengroup.org/onlinepubs/9699919799/utilities/getconf.html">getconf(1)</a> utility.

That is, <code>SysconfVar</code> variables have the same name as the abstract variables
|
|

shown in the <code>sysconf(3)</code> man page. Usually, it's the same as the C
|
|
|
variable name without the leading <code>_SC_</code>.</p>
|
|

<p>All of these symbols are standardized by POSIX 1003.1-2008, but haven't been

implemented by all platforms.</p>
