v8.setHeapSnapshotNearHeapLimit(limit)

• limit <integer>

如果 --heapsnapshot-near-heap-limit 已经从命令行设置或 API 被多次调用，则 API 是无操作的。limit 必须是正整数。有关详细信息，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.
