<p>The Retrieve Operational Descriptor Information (CEEDOD) API retrieves

operational descriptor information about a parameter used in the call to this

API. The operational descriptor communicates additional information about a

parameter, such as size and shape.</p>

<!-- Please NOTE: DO NOT DELETE THIS SECTION if this API has no authorities and locks. -->

<!-- Instead, use the commented out coding below to indicate NONE. -->

<h3>Usage Notes</h3>
|
|
|
|
<ul>
|
|
<li>CEEDOD is implemented as a builtin and therefore cannot have its address
|
|
taken or be called through a procedure pointer.</li>
|
|
|
|
<li>It is an error to use CEEDOD to test an argument that is not a reference
|
|
argument. It is also an error to test an argument that is preceded in the
|
|
argument list by other arguments that are not reference arguments.</li>
|
|
|
|
<li>The results are undefined if you use the CEEDOD API in a function that does
|
|
not specify operational descriptors.</li>
|
|
</ul>
