|

The <code class="methodname">DbEnv::repmgr_site_list()</code> method returns the status of the
|
||
sites currently known by the Replication Manager.
|
||
</p>
|
||
<p>
|
||
The <code class="methodname">DbEnv::repmgr_site_list()</code> method creates a statistical
|
||
structure of type <code class="literal">DB_REPMGR_SITE</code> and copies a pointer to it into a
|
||
user-specified memory location.
|
||
</p>
|
||
<p>
|
||
Statistical structures are stored in allocated memory. If application-specific allocation routines have been
|
||
declared (see <a class="xref" href="envset_alloc.html" title="DbEnv::set_alloc()">DbEnv::set_alloc()</a> for more information),
|
||
they are used to allocate the memory; otherwise, the standard C library
|
||
<span class="bold"><strong>malloc</strong></span>(3) is used. The caller is responsible for deallocating
|
||
the memory. To deallocate the memory, free the memory reference; references inside the returned
|
||
memory need not be individually freed.
|
||
</p>
|
||
<p>
|
||
The following <code class="literal">DB_REPMGR_SITE</code> fields will be filled in:

Environment ID assigned by the Replication Manager. This is the same value that is passed to

Zero or a bitwise inclusive OR of the <code class="literal">DB_REPMGR_ISPEER</code> constant.
|

The <code class="literal">DB_REPMGR_ISPEER</code>
|

value means that the site is a possible client-to-client peer.
