This is similar to @code{getcwd}, but has no way to specify the size of
the buffer. The GNU library provides @code{getwd} only
for backwards compatibility with BSD.

+@vindex PWD
+This @code{get_current_dir_name} function is bascially equivalent to
+@w{@code{getcwd (NULL, 0)}}. The only difference is that the value of
+the @code{PWD} variable is returned if this value is correct. This is a
+subtle difference which is visible if the path described by the
+@code{PWD} value is using one or more symbol links in which case the
+value returned by @code{getcwd} can resolve the symbol links and
+therefore yield a different result.

+This function is a GNU extension.
