2.6.10 - onBufferFull.md

onBufferFull

当缓存区达到最高水位时触发此事件。

function onBufferFull(Swoole\Server $serv, int $fd);

• 设置server->buffer_high_watermark选项来控制缓存区高水位线，单位为字节
• 触发onBufferFull表明此连接$fd的发送队列已触顶即将塞满，这时不应当再向此$fd发送数据

$server->set([
	'buffer_high_watermark' => 8 * 1024 * 1024,
]);

$server->on('onBufferFull', function ($serv, $fd) {

});
