网络模块 (std/net.vix)

类型

pub type sockaddr_in = struct {
    sin_family: u16,
    sin_port: u16,
    sin_addr: u32,
    sin_zero: [u8 * 8]
}

pub type Socket = struct {
    fd: i32
}

pub type Result:[T, E] = Ok(T) | Err(E)

API

pub fn new_tcp(): Result[Socket, string]              // 创建 TCP 套接字
pub fn connect_tcp(sock: Socket, address: sockaddr_in): Result[i32, string]  // 连接

示例

import "std/net.vix"

fn main(): i32
{
    let sock_result = new_tcp()
    match sock_result
    {
        Ok(sock) -> print("Socket created: ", sock.fd)
        Err(e) -> print("Failed: ", e)
    }
    return 0
}

    fn socket(domain: i32, type_: i32, protocol: i32): i32
    fn connect(sockfd: i32, addr: ptr, addrlen: usize): i32
