<p>Qp2dlerror() returns a pointer to a string that provides error information
|
||
|
|
for the most recent dynamic load function (API Qp2dlopen, Qp2dlsym, or
|
||
|
|
Qp2dlclose).</p>
|
||

<h3>Parameters</h3>
|
||
|
|
|
||
|
|
<p>None.</p>
|
||
|
|
|
||
|
|
<br>
|
||
|
|
|
||

|
|

<h3>Authorities</h3>
|
||
|
|
|
||
|
|
<p>None.</p>
|
||
|
|
|
||
|
|
<br>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>Return Value</h3>
|
||
|
|
|
||
|
|
<p>The function result is a pointer to a null-terminated character string (in
|
||
|
|
the job default CCSID). A null pointer is returned if no error occurred during
|
||
|
|
the most recent dynamic load operation. Once Qp2dlerror is called, subsequent
|
||
|
|
calls without an intervening dynamic load error also return a null pointer.</p>
|
||
|
|
|
||
|
|
<p>The ILE <strong>errno</strong> is set and a null pointer is returned for any
|
||
|
|
internal processing error (such as an error converting the string from the
|
||
|
|
i5/OS PASE CCSID to the job default CCSID).</p>
|
||
|
|
|
||
|

|
|
<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>Qp2dlerror is not threadsafe because it may call an i5/OS PASE function
|
||
|
|
that is not threadsafe (dlerror) and uses a buffer in static storage for the
|
||
|
|
error string that is also updated by other dynamic load functions (APIs
|
||
|
|
Qp2dlopen, Qp2dlsym, and Qp2dlclose). Applications may need to serialize use of
|
||
|
|
dynamic load functions and copy the error information string to preserve its
|
||
|
|
contents.</li>
|
||
|
|
</ol>
