<p><strong>Note:</strong> This function can only be used in an i5/OS PASE
program. See <a href="../rzalf/rzalfintro.htm">i5/OS PASE</a> for more
information.</p>
<p>The <strong>_CVTSPP()</strong> function converts the teraspace address in a
tagged space pointer to an equivalent i5/OS PASE memory address.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>source</strong></dt>
<dd>(Input) Pointer to a tagged space pointer or 16-byte null pointer. The
source address must 16-byte aligned.</dd>
</dl>
<br>
<h3>Authorities</h3>
<p><strong>_CVTSPP</strong> requires no authority.</p>
<br>
<h3>Return Value</h3>
<p><strong>_CVTSPP</strong> returns the i5/OS PASE memory address equivalent
of the input tagged space pointer. The result is zero (null) if the input is a
16-byte null pointer or a tagged space pointer that does not contain the
teraspace address equivalent of some valid i5/OS PASE memory address.</p>
<br>
<h3>Error Conditions</h3>
<p>Any error is reported with an i5/OS exception message that the system
converts to an i5/OS PASE signal. See <a href="pase_signals.htm">i5/OS PASE
Signal Handling</a> for information about handling i5/OS exceptions.</p>
<br>
<h3>Usage Notes</h3>
<ol>
<li>_CVTSPP returns an i5/OS PASE memory address regardless of whether there
is currently any memory at that address (as long as the input tagged pointer
contains the teraspace address equivalent of a valid i5/OS PASE memory
address).</li>
</ol>
