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...
以write为例:其函数原型为 size_t write(int fd, const void *buf, size_t nbytes),其操作对象为文件描述符或文件句柄fd(file descriptor),要想写一个文件,必须先以可写权限用open系统调用打开一个文件,获得所打开文件的fd,例如fd=open(/"/dev/video/", O_RDWR)。fd是一个整型值,每新打开一个文件,所...
