其他數據模型很罕見。例如,ILP64(8/8/8:int、long 和指針是 64 位)只會在某些早期 64 位 Unix 系統出現(例如 UNICOS on Cray)。 註解功能特性測試宏值 標準 功能特性 __cpp_unicode_characters 200704L (C++11) 新字符類型 (char16_t 和char32_t) __cpp_char8_t 201
char32_t 是用于 32 位宽字符的无符号整数类型,与 uint_least32_t 为同一类型。 注意任何给定平台上,经由 uint_least32_t 的定义,类型 char32_t 的宽度可能大于 32 位,但存储于 char32_t 类型对象中的实际值将始终拥有 32 位宽度。 示例运行此代码 #include <stdio.h> #include <uchar.h> int main(...
int32_t int64_tsigned integer type with width of exactly 8, 16, 32 and 64 bits respectively with no padding bits and using 2's complement for negative values (provided only if the implementation directly supports the type) int_fast8_t ...

Epoll 关键数据结构 前面提到Epoll 速度快和其数据结构密不可分,其关键数据结构就是: struct epoll_event { __uint32_tevents; // Epoll events epoll_data_tdata; // User data variable }; typedef union epoll_data { void *ptr; int fd; __uint32_t u32; __uint64_t u64; } epoll_data_t...
