[Gevent source code analysis] c-ares asynchronous DNS request, geventc-ares
C-ares is an asynchronous DNS request library. libcurl, libevent, and wireshark all use c-ares. Before gevent1.0, libevent is used,
Therefore, its DNS request uses

1. Heap Sorting
The definition of heap sort and thought can refer to Baidu Encyclopedia: Heap Sort
In a nutshell, heap sequencing is an improved sort of selection, the improvement is that each time you make a choice, not only the largest number of the selection, but also the sorting process of some of the operations recorded, so in the subsequent sort can be used, and the idea of grouping in the inside, thereby improving the sorting efficiency, Its efficiency is O (N*LOGN).

Preface:
Android has added many drivers based on Linux kernel. The alarm driver is the simplest one. The entire file contains more than 500 lines. As the beginning of a series of articles driving code analysis, I tried to carefully analyze almost all of the function code of this driver, hoping to use this as a good start for reviewing the android driver source
