我有一位创造共同记忆区域的作者,我想确保读者在撰写人准备就绪之前不开该地区。 我这样做的粗略方式是作者们,会以只读的方式开课。 该地区一旦得到正确建造,档案就存档。 这是幸运的,我不能假装()记录员更改许可。 任何建议(该区域没有做些什么?)
为什么会 y? 部分原因在于没有平衡法(假定是)告诉我,共有记忆区在哪里生活(例如/dev/shm)。 有一些平衡法,可以看一看,我更喜欢不复制,但如果没有人能够给我更好的解决办法,可能别无选择。

你们当然可以使用微粒,这允许你在你选择的目录中使用一个档案(也许是一种选择,可以把它放在斜线上)。
但是,为了解决lock锁问题,也许你们应该利用共享区域的双向,或者(在推动下)仅仅锁在案卷上。
但是,如果你试图把它当作一个问题来做,那么你也许应该只使用一种更令人怀疑的IPC物体。
