<p>The <strong>QlgRmdir()</strong> function, like the <strong>rmdir()</strong>
|
||
|
|
function, removes a directory, <em>path</em>, provided that the directory is
|
||
|
|
empty; that is, the directory contains no entries other than "dot"
|
||
|
|
(<strong>.</strong>) or "dot-dot" (<strong>..</strong>). The difference is that
|
||
|
|
the <strong>QlgRmdir()</strong> function takes a pointer to a Qlg_Path_Name_T
|
||
|
|
structure, while <strong>rmdir()</strong> takes a pointer to a character
|
||
|
|
string.</p>
|
||
|
|
|
||
|
|
<p>Limited information on the <em>path</em> parameter is provided here. For
|
||
|
|
more information on the <em>path</em> parameter and for a discussion of
|
||
|
|
authorities required, return values, usage notes, and related information, see
|
||
|
|
