大家好,关于内核中semaphore的使用?
大家好,最近碰到一个疑惑,让我头疼不已,linux在核心态只能有一个进程在运行,而semaphore又是为了进程同步设计而设计的,那么semaphore到底可以用于什么方面那?而说得semaphore在user context中应用很大?我对user context理解的可能不是很透彻,麻烦各位高手帮忙?感激不尽!!!! all three books, LDD2 ULK2 and QJFX has stuff about semaphore. can u read them? At least they describe things more clear than I do.:-D
if u can not find the books. let me know.
