In Nixpkgs, these three platforms are defined as attribute sets under the
names <literal>buildPlatform</literal>, <literal>hostPlatform</literal>, and
<literal>targetPlatform</literal>. They are always defined as attributes in
the standard environment. That means one can access them like:
names <literal>buildPlatform</literal>, <literal>hostPlatform</literal>,
and <literal>targetPlatform</literal>. All three are always defined as
attributes in the standard environment, and at the top level. That means
one can get at them just like a dependency in a function that is imported
with <literal>callPackage</literal>:
<programlisting>{ stdenv, buildPlatform, hostPlatform, fooDep, barDep, .. }: ...buildPlatform...</programlisting>
, or just off <varname>stdenv</varname>:
<programlisting>{ stdenv, fooDep, barDep, .. }: ...stdenv.buildPlatform...</programlisting>
.
