对于C语言的项目,一些文件动辄几千行代码,上百个函数体,理解起来颇有些费劲。这个时候我们可以使用calltree工具对代码进行静态分析,然后产生调用关系树,使得我们可以对代码的构成有个初步的认识。这样可以让我们站在高处,俯览全局,制定出一个着实可行的阅读理解方案。(题外话:静态分析中发生不准确的现象很常见) ...

a loop in which thread waits for incoming notifications (commands). After receiving a command the thread executes this command. Incoming commands are handled sequentially in the thread task procedure. Simultaneously, the thread may set the current thread activity status to inform the owner thread. ...
ST当前的状态是,整个环境处于空闲状态,所有threads的请求处理都已经完成,也就是RUNQ为空。这时在_st_idle_thread_start维护了一个主循环(类似于event loop),主要负责三种任务:1.对IOQ所有thread进行I/O复用检测;2.对SLEEPQ进行超时检查;3.将idle thread调度出去,代码如下:...
