Socket基础类
提供跨平台的socket基础操作,是所有socket类的基类。 支持移动语义,不支持拷贝。
主要功能:
- Socket创建和关闭
- 阻塞/非阻塞模式设置
- Socket选项配置(地址重用、端口重用、TCP_NODELAY、KeepAlive等)
- 收发缓冲区大小设置
- 超时设置
- 本地/远程端点查询
- 绑定和监听
- 移动语义支持
使用示例:
sock.
open(AF_INET, SOCK_STREAM, 0);
if (local) {
}
static NEFORCE_NODISCARD ip_address any(ports port=ports::undef, int family=AF_INET) noexcept
获取通配地址
bool set_tcp_nodelay(bool enable=true) noexcept
设置TCP_NODELAY(禁用Nagle算法)
bool set_reuse_address(bool enable=true) noexcept
设置地址重用(SO_REUSEADDR)
void bind(const ip_address &endpoint)
绑定socket到本地地址
NEFORCE_NODISCARD optional< ip_address > local_endpoint() const
获取本地端点地址
bool set_nonblocking(bool enable) noexcept
设置非阻塞模式
void listen(int backlog)
开始监听连接(TCP)
void open(int family, int type, int protocol)
打开socket
void println(Args &&... args)
打印多个值并换行
