＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ PHP5里的接口（interface）到底有什么用？ 看了些资料，依然觉得很迷糊，php5的接口只是提供了一些空的function而已，实际的方法依然在各个class里面，并且要使用这些function的时候依然要先实例化这些class，那么，接口，到底起个什么作用？？ ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝...

interface can have three kinds of members: 1. field 2. method 3. nesting(嵌套)class or interface In the interface, the field is always public, static and final. But generally we can omit(省略)them. Them must have initalize values, because final field can not be null. The methods in interface are always abstract and public, they can not be native, synchronized or strctfp. They can't be static too...

和内核沾点边,来这里求助了, 我想在用户层分别得到使用磁盘,cpu最高的几个进程(或者进程组), 不知道该如何实现, linux下有个iotop能以类似top(1)的形式显示进程的I/O利用情况,但是那个软件是python写的,我读起来很(非常)吃力, 他大致是先在从proc读到进程列表,然后又读了 /proc/xxpid/status, 然后用netlink获得某些进程的taskstats 不清楚从proc pid status下他想读什么,貌似是读进程的uid,gid之类的东东 [code] // /usr/incl...
