A wrapper for the POSIX <code class="function">lstat()</code> function. The <code class="function">lstat()</code> function is
like <code class="function">stat()</code> except that in the case of symbolic links, it returns
information about the symbolic link itself and not the file that it
refers to. If the system does not support symbolic links <a href="glib-File-Utilities.html#g-lstat"><code class="function">g_lstat()</code></a>
is identical to <a href="glib-File-Utilities.html#g-stat"><code class="function">g_stat()</code></a>.

<p>
A wrapper for the POSIX <code class="function">unlink()</code> function. The <code class="function">unlink()</code> function 
deletes a name from the filesystem. If this was the last link to the 
file and no processes have it opened, the diskspace occupied by the
file is freed.
</p>
<p>
See your C library manual for more details about <code class="function">unlink()</code>. Note
that on Windows, it is in general not possible to delete files that
are open to some process, or mapped into memory.</p>

<p>
A wrapper for the POSIX <code class="function">remove()</code> function. The <code class="function">remove()</code> function
deletes a name from the filesystem.
</p>
<p>
See your C library manual for more details about how <code class="function">remove()</code> works
on your system. On Unix, <code class="function">remove()</code> removes also directories, as it
calls <code class="function">unlink()</code> for files and <code class="function">rmdir()</code> for directories. On Windows,
although <code class="function">remove()</code> in the C library only works for files, this
function tries first <code class="function">remove()</code> and then if that fails <code class="function">rmdir()</code>, and
thus works for both files and directories. Note however, that on
Windows, it is in general not possible to remove a file that is
open to some process, or mapped into memory.</p>
