|
|
|
|
<p>The <strong>QlgRenameKeep()</strong> function, like the <strong>
|
|
Qp0lRenameKeep()</strong> function, renames a file or a directory specified by
|
|
<em>old</em> to the name given by <em>new</em>. The difference is that the
|
|
<strong>QlgRenameKeep()</strong> function takes pointers to Qlg_Path_Name_T
|
|
structures, while <strong>Qp0lRenameKeep()</strong> takes pointers to character
|
|
strings.</p>
|
|
|
|
<p>Limited information on the <em>old</em> and <em>new</em> parameters is
|
|
provided here. For more information on these parameters and for a discussion of
|
|
the authorities required, return values, and related information, see <a href=
|
|
"renamekp.htm">Qp0lRenameKeep()</a>--Rename File or Directory, Keep "new" If It
|
|
Exists.</p>

|
<h3>Parameters</h3>
|
|
|
|
<dl>
|
|
<dt><strong><em>old</em></strong></dt>
|
|
|
|
<dd>(Input) A pointer to a Qlg_Path_Name_T structure that contains a path name
|
|
or a pointer to the path name of the file to be renamed. For more information
|
|
on the Qlg_Path_Name_T structure, see <a href="../apiref/pns.htm">Path name
|
|
format</a>.<br>
|
|
<br>
|
|
</dd>
|
|
|
|
<dt><strong><em>new</em></strong></dt>
|
|
|
|
<dd>(Input) A pointer to a Qlg_Path_Name_T structure that contains a path name
|
|
or a pointer to the path name of the new name for the file. For more
|
|
information on the Qlg_Path_Name_T structure, see <a href="../apiref/pns.htm">Path name
|
|
format</a>.</dd>
