IO event loop parsing and libevio event parsing in libev 1. Basic data structure of IO events ev_io Struct ev_io this struct is an IO monitor. All events in libev have their own struct, such as ev_time and ev_io. The base class ev_watcher is defined as follows: typedef struct ev_watcher{ int active; int pending; int priority; void *data; void (*cb)(struct ev_loop *loop, struct ev_watcher *w, int revents);} In the base class, "acti

processed will be checked and executed: 1) returned from a hardware interrupt code 2) In the ksoftirqd kernel thread 3) in the code that explicitly checks and executes the Soft Interrupt to be processed, such as the network subsystem The Soft Interrupt should be executed in the do_softirq () function: Asmlinkage void do_softirq (void) { _ U32 pending; Unsigned long flags; If (in_interrupt ()) Return; Local_irq_save (flags );

The representation of the signal in the kernelThe processing action of the signal is called the signal recursion (Delivery), the signal from the generation to the state between the recursion, called signal Pending (Pending). A process can choose to block (block) a signal. When the blocked signal is generated, it remains in the pending state until the process has

in the business is too small, in the short term in the social media and the ontology service providers, can not see Google's breakthrough point, These services must have a sufficient user base to be effective. I personally think the next possible breakthrough lies in the Android platform, but I'm afraid it still depends on the killer apps outside the maps. Google has a very big difficulty in information integration: How do you implement the concatenation of variable-current information? This is

, the social gaming company that created the miracle of gardening, valued as much as $9 billion trillion, and Twitter, the founder of the unprofitable microblog, was said to be worth 10 billion dollars. Groupon has rejected Google's 6 billion-dollar takeover request, and some believe Groupon will hit $25 billion trillion once it goes public. Of course, the highest valuations are facebook,830 billion dollars

Typically, a soft interrupt marks the interrupt handler before it returns, making it run at a later time. in the following places. The soft interrupts to be processed are checked and run:1. After

structure of the process contains the data member about the pending signals in the process: struct sigpending pending: Struct sigpending { Struct sigqueue * head, * tail; Sigset_t signal; }; The Third Member is all pending signal sets in the process. The first and second members point to the beginning and end of a sigqueue-type structure chain (called "

The selected version is the latest version: libev-4.04. The libev code is concise. In addition to encapsulation files such as the efficient I/O model, the core files are ev. h and ev. c, of which ev. c contains about 4000 lines. A large number of macros are used in the code, and macros are nested. To facilitate understanding of libev code, the macro is restored here.
