<b>Description: DbEnv::repmgr_site_list</b>
<p>The DbEnv::repmgr_site_list method returns the status of the sites currently
known by the replication manager.</p>
<p>The DbEnv::repmgr_site_list method creates a statistical structure of type
DB_REPMGR_SITE 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 href="../api_cxx/env_set_alloc.html">DbEnv::set_alloc</a> for more
information), they are used to allocate the memory; otherwise, the
standard C library <b>malloc</b>(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 DB_REPMGR_SITE fields will be filled in:</p>
<br>
<b>int eid;</b><ul compact><li>Environment ID assigned by the replication manager.
This is the same value that is passed to the application's
event notification function for the <a href="../api_cxx/env_event_notify.html#DB_EVENT_REP_NEWMASTER">DB_EVENT_REP_NEWMASTER</a> event.</ul>
<b>char host[];</b><ul compact><li>Nul-terminated host name.</ul>
<b>u_int port;</b><ul compact><li>TCP/IP port number.</ul>
<b>u_int32_t status;</b><ul compact><li>One of the following list of constants: <a name="DB_REPMGR_CONNECTED">DB_REPMGR_CONNECTED</a>,
<a name="DB_REPMGR_DISCONNECTED">DB_REPMGR_DISCONNECTED</a>.</ul>
<br>
<p>The DbEnv::repmgr_site_list method may be called at any time during the life of the
application.</p>
<p>The DbEnv::repmgr_site_list method
either returns a non-zero error value
or throws an exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
</p>
<b>Parameters</b> <br>
<b>countp</b><ul compact><li>A count of the returned structures will be stored into the memory
referenced by <b>countp</b>.</ul>
<b>listp</b><ul compact><li>A reference to an array of structures will be stored into the memory
referenced by <b>listp</b>.</ul>
