<p>The <em>endhostent_r()</em> function is used to close the host database
|
||
|
|
file. The file is opened by those functions that retrieve information about a
|
||
|
|
host (for example, <em>gethostent_r()</em>).</p>

||
|
|
|
||
|
|
<h3>Parameters</h3>
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt>struct hostent_data *<strong>hostent_data_struct_addr</strong>
|
||
|
|
(input) </dt>
|
||
|
|
|
||
|
|
<dd>Specifies the pointer to the hostent_data structure, which is used to pass
|
||
|
|
and preserve results between function calls. The field host_control_blk in the
|
||
|
|
hostent_data structure must be initialized with hexadecimal zeros before its
|
||
|
|
initial use. If compatibility with other platforms is required, then the entire
|
||
|
|
hostent_data structure must be initialized to hexadecimal zeros before initial
|
||
|
|
use.</dd>
|
||
|

<h3>Authorities</h3>
|
||
|
|
|
||
|
|
<p>No authorization is required.</p>
|

|
|
||

|
<br>
|

|
<h3>Return Value</h3>
|
||
|
|
|
||
|
|
<p>The <em>endhostent_r()</em> function returns an integer. Possible values
|
||
|
|
are:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>-1 (unsuccessful call)</li>
|
||
|
|
|
||
|
|
<li>0 (successful call)</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>The <strong>struct hostent_data</strong>denoted by
|
||
|
|
<strong><em>hostent_data_struct_addr</em></strong> is defined in
|
||
|
|
<strong><netdb.h></strong>.</p>
|
||
|
|
|
||
|
|
<br>
|
||
|
|
<h3>Error Conditions</h3>
|
||
|
|
<p>When the <em>endhostent_r()</em> function fails, <em>errno</em> can be set
|
||
|
|
to:</p>
|
||
|
|
<dl>
|
||
|
|
|
||
|
|
|
||
|
|
<dt><em><samp>[EINVAL]</samp></em></dt>
|
||
|
|
<dd><p>The hostent_data structure was not properly
|
||
|
|
initialized to hexadecimal zeros before initial use. For corrective action, see
|
||
|
|
the description for structure hostent_data.</p></dd>

<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>When the _XOPEN_SOURCE
|
||
|
|
macro defined to the value 520 or greater, the host file is always closed. When
|
||
|
|
the _XOPEN_SOURCE macro is not so defined, the host file will not be closed if a
|
||
|
|
<em>sethostent_r()</em> call with a nonzero parameter value was previously done.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>The iSeries Navigator or the following CL commands can be
|
||
|
|
used to access the host database file:<br>
|
||
|
|
<br>
|
||
|
|
<ul>
|
||
|
|
<li>ADDTCPHTE (Add TCP/IP Host Table Entry)</li>
|
||
|
|
|
||
|
|
<li>RMVTCPHTE (Remove TCP/IP Host Table Entry)</li>
|
||
|
|
|
||
|
|
<li>CHGTCPHTE (Change TCP/IP Host Table Entry)</li>
|
||
|
|
|
||
|
|
<li>RNMTCPHTE (Rename TCP/IP Host Table Entry)</li>
|
||
|
|
|
||
|
|
<li>MRGTCPHT (Merge TCP/IP Host Tables)</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>When you develop in C-based languages and an application is compiled with
|
||
|
|
the _XOPEN_SOURCE macro defined to the value 520 or greater, the <em>endhostent_r()</em>
|
||
|
|
API is mapped to <em>qso_endhostent_r98()</em>.</li>
|
||
|
|
</ol>
