<p>The Unregister Call Stack Entry Termination User Exit Procedure (CEEUTX) API
is used to unregister a user-defined procedure that was previously registered
by the Register Call Stack Entry Termination User Exit Procedure (CEERTX) API.
The CEEUTX API operates on the call stack entry termination user exits that are
registered for the call stack entry from which the CEEUTX API is called.</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>Authorities and Locks</h3>
<!-- Use this if there are no authorities and locks. -->
<p>None.</p>

<h3>Required Parameter</h3>

<dt><strong>fc (output)</strong></dt>

<h3>Usage Notes</h3>
<ul>
<li>Registered call stack entry termination user exit procedures are
automatically unregistered upon the return from the call stack entry for which
they are registered.</li>
<li>If the same procedure is registered for the call stack entry more than
once, the CEEUTX API processes the registrations in LIFO order.</li>
<li>The message CEE0257 occurs if the pointer contained in <em>procedure</em>
is not a procedure pointer.</li>
</ul>
