Some key structures in libev source code

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. The ev_watcher struct (its member is the public part of another structure ): Typedef struct ev_watcher { Int active; // activati

Overload, override, and hide in C ++)

Before writing a question, give a few keywords in Chinese and English, overload, override, and hide ). In early C ++ books, people who translate may not be familiar with professional terms (nor can they blame them. They are not engaged in computer programming and they are specialized in English ), overload and override are often incorrect! Let's first look at some code and its compilation results.

At that time, segment address addressing was adopted. Physical addresses include segment addresses and intra-segment addresses. Long pointers can be used for addressing different segments, while NP, or near pointers, can be used for addressing within the same segment. However, 32-bit Win
