原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了Golang中github.com/lxc/lxd/shared.Jmap类的典型用法代码示例。如果您正苦于以下问题：Golang Jmap类的具体用法？Golang Jmap怎么用？Golang Jmap使用的例子？那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。



在下文中一共展示了Jmap类的12个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: snapshotPost

	_, err = os.Stat(newDir)

	} else if err == nil {
		return Conflict
	}

	/*
	 * TODO: do we need to do something more intelligent here? We probably
	 * shouldn't do anything for stateful snapshots, since changing the fs
	 * out from under criu will cause it to fail, but it may be useful to
	 * do something for stateless ones.
