C++ (Cpp) queue_listen Examples

Example #1

File: async.c Project: asurinsaka/postgresql-8.2.19-lru

/*
 * Async_UnlistenAll
 *
 *		This is invoked by UNLISTEN "*" command, and also at backend exit.
 */
static void
Async_UnlistenAll(void)
{
	if (Trace_notify)
		elog(DEBUG1, "Async_UnlistenAll(%d)", MyProcPid);

	queue_listen(LISTEN_UNLISTEN_ALL, "");
}

Example #2

File: async.c Project: chrishajas/gpdb

/*
 * Async_Listen
 *
 *		This is executed by the SQL listen command.
 */
void

{
	if (Trace_notify)
		elog(DEBUG1, "Async_Listen(%s,%d)", relname, MyProcPid);

}

Example #3

File: async.c Project: chrishajas/gpdb

 * Async_UnlistenAll
 *
 *		This is invoked by UNLISTEN * command, and also at backend exit.
 */
