v8.setHeapSnapshotNearHeapLimit(limit)

• limit <integer>

如果命令行中已经设置了 --heapsnapshot-near-heap-limit，或者 API 被调用超过一次，该 API 将不会执行任何操作。limit 必须是正整数。有关更多信息，请参阅 --heapsnapshot-near-heap-limit。

【The API is a no-op if --heapsnapshot-near-heap-limit is already set from the command line or the API is called more than once. limit must be a positive integer. See --heapsnapshot-near-heap-limit for more information.】
