<p>The <strong>QlgMkfifo()</strong> function, like the <strong>
|
|
mkfifo()</strong> function, creates a new FIFO special file whose name is
|
|
defined by <em>path</em>. The difference is that the <strong>
|
|
QlgMkfifo()</strong> function takes a pointer to a Qlg_Path_Name_T structure,
|
|
while <strong>mkfifo()</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 other
|
|
parameters, authorities required, return values, and related information, see
|
|
<a href="mkfifo.htm">mkfifo()</a>--Make FIFO Special File.</p>

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