readline函数里面的read是一个字节的读取,长度长了之后循环调用函数次数很多,会不会影响性能呢? 请问这里是怎么考虑的
程序运行到这个,open chatRome.db 失败,我的解决办法是添加所有者的权限,还是打开失败
跪求答案。
Socket/ChatRome -- select/server/chat.c
Line 367 in 5090503
在Socket/client/config.h 文件中的ListNode* userList 前面需要加上extern。
ssize_t readline(int fd, char *vptr, size_t maxlen) 返回值是ssize_t 是unsigned 类型,但是函数内有return -1;
这个代码片段在tcp server中摘出来的
perror("bind error");
exit(1);
有一天我看到了这篇文章.里面在绝大多数的perror和return之前,都会关闭socket.
而大部分我能找到的案例中,都只有最后 return前一个孤零零的关闭 socket. 对此不知道大佬有何看法/???
