函数原型:ssize_t write(int fd, const void *buf, size_t count); 功能:从buf里写count个数据到fd指向的文件中。 返回值:成功返回写入的字节数,出错返回-1。 使用举例: int test2() { // 1、对文件进行写入 umask(0); int fd = open("log.txt", O_WRONLY|O_CREAT, 0664); const char* source...
Remember, this method only displays the total number of all items (such as "text files", ".sh files", and "directories") and does not count individual files. At least, Ubuntu's default file browser Nautilus doesn't, but others, like Dolphin Browser, do show you more data. Check the ...
9. vm.max_map_count:该参数控制系统允许的最大内存映射数量。默认值为65530,建议值为262144。 10. net.core.somaxconn:该参数控制系统TCP连接的最大排队数量。默认值为128,建议值为1024。 11. net.core.netdev_max_backlog:该参数控制系统网络设备接收数据包的队列大小。默认值为1000,建议值为5000。
